Competitiveness of Polish small and medium businesses

on the EU markets

 

Introduction

The present situation of world economy and fears of possible recession in Polish economy forces to take extraordinary steps in order to compensate effects of the global crisis in our country. Small and medium businesses (SMB) growth is one of such methods. The functioning of this group is desirable in view of national economy since it stabilizes the economic processes and underlies the economic growth, which in the face of current crisis is extremely important. 

Small and medium businesses proved to be useful in times of recession because they have significantly mitigated the economic transformations in Poland in the beginning of 1990s by filling the gaps in economy caused by the bankrupt national companies. In addition, small and medium businesses may effectively operate in wake of global crises, so called “financial”, above-all owing to the simplified finance management system (predominance of internal financial sources in the investment processes) and focus on the local market. On the other hand, small and medium businesses are forced to operate within the circumstances of open European market, that is to say greater competition. In such case it is extremely important to build completely new competitive advantages which would enable the businesses to compete on such demanding market. The capacity to compete, especially in long term is determined by applying sustainable competitive advantages since only sustainable competitive advantage enables to earn profits above average.

This article aims at presenting the key sources of competitive advantage within Polish small and medium businesses present on the European market, the fact which seems to be extremely important in the event of circumstances to face in running the economic business in the beginning of the XXI century.

The sources of competitive advantage in business 

The recognition of sources of competitive advantage and especially their position within or outside the business is a starting point in assessing its competitiveness. Nowadays, the sources of competitive advantage in business are not referred strictly to the trade but mainly to capital flows, technological innovation, institution quality and management, and their influence on productivity factors and factual income growth per capita.[1] In the conditions of present competitiveness, the sources of competitive advantage become less significant including those which are connected with: copyrights, property, brand, patents, technological knowledge, the marketing management knowledge, computer science and the ability to its application in order to achieve additional benefits (f. inst. offer of new products which have high income flexibility of demand). Global competitiveness causes that one of the methods to create competitive advantage have become individualization and high level of processed products from the customer point of view and development of cooperation with other companies, by making technological alliances which enable to develop new competences, technologies, products and services.[2] The possibility of business segmentation on the market and adaptation of its own product offer is the source of advantage.[3]

Knowledge of the sources of competitive advantage and their influence on the advantage character requires careful examination of both theoretical conceptions concerning this issue and also familiarity with differences appearing thereof. Research on the sources of competitive advantage became more relevant in the beginning of 1990s as a result of strong increase of national and international competitiveness and also progressive process of economy globalization. The transformations in these period started to create new possibilities for business development and created new kinds of competitive activities which remarkably influenced the change of approach to the impact of competitive advantage on business competitiveness. The most leading concepts formulated in 1990s are: M.E. Porter’s idea about sources of competitive advantage of businesses and nations, concept of core competence of G. Hamel and C. Prahalada’s corporation, the company resources concept by J. Barney, the concept of distinctive capabilities of J. Kay, time-based competitiveness concept by G. Stalk and the conception of learning organizations by P. Senge.[4] The above mentioned concepts of business competitive advantage had a great impact on understanding the essence of competitive advantage, but also how its sources were perceived and searched. These concepts contributed to create theory on sources of competitive advantage based on the market factors and its resources. Moreover, on their basis there were developed new concepts, f. inst. the concept of knowledge-based enterprise, concept of virtual business and competitive concept based on information and computer systems.

   What sheds a completely new light on the creation of advantage in today’s businesses is departure from approved framework and recognition that the sources of competitive advantage may in parallel be elements within the business but also in the market surrounding, and related herewith distinctive capabilities and strategic resources, time, information, information technology, knowledge and learning. In present economic circumstances the reasonable solution seems to be accepting the assumption which says that building the sustainable competitive advantage requires first and foremost to carry out a detailed analysis of resources and capabilities of business, completed with analysis of external surrounding. At the same time, this situation reveals that there is no universal model showing the way, time and place to build sustainable competitive advantage. It turns out that this process is strongly connected with the conditions of business operation and depending on circumstances, the main source of competitive advantage may be either proper resources and skills or conditions imposed by the competitive surrounding. Consequently, the competitive advantage becomes the derivative of new resources and skills development or responsiveness to changing external conditions.

Contemporary reflections on the issue of sources of competitive advantage refer to the concept of resources and indicate the importance of sources of competitive advantage lying within the business, especially to real capital and skills which create exceptional and unique relations according to its elusiveness, difficulty of imitation and relation to knowledge. This  relates to the rapid spread of all innovative and individualized solutions. The reason being that more and more businesses have a free access to new technologies and each product may be easily copied. The grounds of today’s business competitiveness are real capital, such as: human resources, market resources, and administrative and technological resources and skills, including design, research and development, technological and productive skills, marketing and logistic skills, human management skills, finance management skills and learning skills, knowledge and information management skills. Within their activities the businesses have to strictly apply knowledge management, care about employees and their development, provide conditions for creative work and aim at mastering effective learning skills quicker than competitors. Nowadays human resources and related with it knowledge is the significant source of innovative ideas and new technologies, in the case of which even the capital becomes only a derivative. In the foreground have been activities encouraging business and connected with it employees to constant learning and improving their skills in the field of activities which are difficult to imitate. From the very beginning of business establishment, businesses shall strive to be “intelligent organizations”, since learning increases the ability to respond to the incentives coming from surrounding and significantly influence the results obtained during running the business. No less important seems to be the desire to leave behind the market rivals by increasing the technological distance and being innovative and rationalistic. In the attempts to gain competitive advantage, the business must understand the relation between sectors, which is defined on the basis of skills, technology and products and the market, specified according to the customers and their needs. The sector type which the business belong to has a considerable impact on skills development and organization of the activities in respect of added value, hence the market on which the business wants to work and customers’ needs together decide upon business final success.[5]      

In the age of progressive intensity of competitiveness and complication of mutual relations between businesses, the competitiveness depends mainly on the persistence and time of acquired advantage over the competitors. Consequently, every current business has to endeavour to gain competitive advantage, which will be sustainable, noticeable and considerable for the customer. Such advantage shall be built on the basis of knowledge and experience, always by satisfying specific customer requirements more effectively than the competitors. As a priority the businesses shall rebuild their organizational structures in order to adjust them to the most possible effective way to take advantage of their own power and also constantly changing circumstances. This remains to be necessary to create universal internal structures which would enable to perform extraordinary tasks and achieve the intended objectives, then structures of high learning capabilities, fast mode of action and responsiveness to extensive changes, highly qualified skills of perception and developing new skills. In order to survive and achieve success on the contemporary highly competitive market, it is no longer sufficient only to identify the sources of competitive advantage. One shall respectively follow them, that is to discover, develop them and in the right moment “render” into the market competitive advantage. Only well-considered planned business activities according to their resources and skills and its knowledge-based configuration and precise experience, in view of selected market and respective time allow to gain successful competitive advantage.

Undoubtedly one may claim that efficient operation and further business development depends on the manner of development, including efficient responsiveness and simultaneous surrounding shaping, in which the business exists. Though, resource-based concepts seems to be more useful from the point of view of key sources identification of business competitive advantage, one shall remember about the remarkable role which plays position approach and make efforts to take advantage of the conclusions coming from all considerations to this issue.

Sources of advantage within Polish small and medium businesses on the EU market

Poland’s membership to the European Union have opened tremendous opportunities for all Polish businesses to develop, hence the issue of finding such sources of competitive advantage that could compete on the international markets became extremely important. In fact, success of Polish businesses was determined by the flexibility to changing micro and macroeconomic conditions and elimination of weak points, such as: unsatisfying product and service quality compared with competitors, inadequate supply of financial capital and real capital, low level of marketing management knowledge, lack of experience and strategy of action or low level of investments. Polish businesses acquired direct access to the respective Member States markets which launched into sales growth, the quality improvement, search for strategic investors, improvement of own efficiency and acquisition of new technologies, capital or supply sources. One shall not forget that EU market is very demanding and does not allow to operate on without due level of competitiveness.

As a result, Polish small and medium businesses should continuously strive for improving and developing new elements which contribute to their success on the market. Operation in the age of all-European recession is even more challenging than ever before and requires increased efficiency.

In the attempt to assess the competitiveness of Polish small and medium businesses against international surrounding there can be used thesis quoted in literature saying that the competitiveness of Polish economy depends on the adaptability to fast implementation of innovative technological, technical, manager, and organizational solutions.[6] In the case of small and medium businesses, the reflection of competitiveness level, expressed mainly by: changes within the scope of administration of innovative technological, technical, manager and organizational solutions is also the internationalization level of these businesses. It is believed that small businesses fail to succeed in this field. Most researches of SMB sector carried out before Poland’s accession to the European Union indicate the following key factors of this situation: focus on local market, at best on national market and poor economic and financial situation. These two reasons still constitute major barriers to international operation of these businesses. On the other hand, low level of internationalization in current circumstances decide upon their strength. Poland’s integration with the European Union significantly facilitated the opportunities of operation on European markets, especially for small and medium businesses which as opposed to large entities do not have adequate personnel and capital resources of this kind.  

Small and medium businesses from the European Union considered quality and manner of customer service as their prevailing competitive advantages.[7] Price competitive advantage and localization were placed only on the third position. However, as W. Szymański claims: Polish enterprises, especially small and medium businesses have based their competitiveness mainly on traditional, easily-imitable competitive advantages which include: relatively low costs of labour force and raw materials due to lowered price of Polish currency.[8] Seldom have small and medium businesses competed on the grounds of more distinctive features such as non-price elements, examples being punctuality and high quality of order execution, uniqueness of the service, product etc. Reliance of competitive strategies of Polish small and medium businesses on higher factors enables to compete on the market only in short or medium-term plans since capability to compete in long-term demands from small and medium businesses application of advantages of the higher order.[9]

The College of Strategic Management of SGH [Warsaw School of Economics] carried out the research that revealed changes in the approach of businesses from small and medium businesses sector to the issue of competitiveness, especially those which decided to sell their products and services on the European market.[10] Among the businesses participating in the  questionnaire, more than 44 per cent used the strategies based on cost leadership, about 15 per cent strategies based on special relations with customers, 12 per cent strategies involving time-based advantage, 11 per cent competed on the basis of products brand and company reputation and only 7,5 per cent have built their competitiveness on quality-based advantage.[11] However, amongst all sources of competitive advantage which were considered as an essential elements of competitiveness, the competitive cost of labour was mentioned most frequently – confirmed by 70 per cent respondents.

Passing on now to respective groups of SMB sector, it was noticed the following dependences. In the small business group, amongst the sources of competitive advantage the first place according to the frequency of ratings took (nearly 13 per cent) originating competitive technology, the second position (11,5 per cent) belonged to competitive labour costs in Poland, though on the third position was (10 per cent) special human relations inside the company (illustration 1).

Within the group of small business, which awarded all sources of competitive advantage jointly with 1500 points of note, the first place ranking according to the obtained number of points earned originating competitive technology (328 points), the second place competitive labour costs in Poland (199 points), and the third one capabilities to learn respondents’ preferences and behaviours (134 points).

Analysed small businesses hardly ever did indicate such sources of competitive advantage as: production in the countries of very cheap labour force (no ratings) and advantage in marketing skills, non-originating competitive technology, imported patterns or components and other sources of advantage (with the frequency of ratings: 1,3 per cent).  The least points were granted to the following sources of competitive advantage: production in low-cost labour countries (0 points), imported patterns or components (8 points) and other sources of advantage (10 points).

Within the medium businesses the leading places occupied the following sources of competitive market advantage according to the number of ratings: competitive labour costs in Poland (13,4 per cent), capabilities to learn respondents’ preferences and behaviours (19 per cent) and originating competitive technology, high integration of marketing with production, supply, etc. and capabilities to learn new technologies (8,5 per cent ) (Illustration 2).

Within the group of medium businesses which granted to all indicated sources of competitive advantage totally 2700 points in the research, on the first position were: competitive labour costs in Poland (540 points), second place took originating competitive technology (295 points), and the third one careful selection of market expansion fields and their flexible changes and  capabilities to learn respondents’ preferences and behaviours (265 points). The least frequently were indicated such sources of competitive advantage as: others, not included in the advantage source questionnaire and imported pattern or components (no ratings) and production in the countries of very cheap labour force (with the frequency of ratings below 1 per cent). The sources of competitive advantage which obtained the least points within the group of medium businesses turned out to be respectively: imported patterns or components (0 points), others, not included in the advantage source questionnaire (0 points) and production in the countries of very cheap labour force (20 points) and application of orders inside the company (35 points).

In the Polish medium businesses’ opinion the most important source of competitive advantage, favourable to succeed on the EU market were low costs of labour force in Poland which still enable to compete with foreign companies. However, apart from the mentioned source, medium businesses indicated also the urge to use the originating technology in building sustainable competitive advantage, capabilities connected with the selection of market expansion fields and their flexible changes, capabilities to learn respondents’ preferences and behaviours, capabilities to learn new technologies and integration of marketing steps with productive and logistic strategy.

In the group of small business the most important source of competitive advantage according to the activities on the European Union market was competitive originating technology, and then competitive labour costs in Poland, careful selection of market expansion fields with their flexible changes and capabilities to learn respondents’ preferences and behaviours.

In the case of small and medium business one shall very positively remark high ranking of originating technology application as a source of competitive advantage. The fact that determines the success of Polish small and medium businesses in this field is that businesses sell mainly (80 per cent for small and 67 per cent for medium businesses) private label brand products and services (table 1). In the case of small businesses it happens even more frequently than in the group of large enterprises. This conclusion proves also that least remarkable or even meaningless sources of competitive advantage are considered similarly like in the case of ratings and assessment of respective sources: imported patterns and components, production in the countries of very cheap labour force and non-originating competitive technology playing the least important role.

The carried out researches show that Polish small and medium businesses start to notice the key role of their own internal resources and skills of building sustainable competitive advantage over other participants of market play. Polish entrepreneurs begin to perceive the mechanisms between respective skills and need of their usage, whereas the effectiveness of actions based on internal sources of competitive advantage will require from managers a great creativity. The usage of originating technology, being recognized in the case of small businesses as a most important, and in the case of medium businesses as a second one amongst the most important competitive advantages decides upon change of strategic orientation amongst those businesses, that is a change from short-term to long-term orientation. The choice of this factor as one of the main competitive advantage shall be correlated with the fact that majority of the questioned businesses export private label products. Adapting such strategy confirms also the change of attitude towards business management among Polish entrepreneurs.

Change in strategic orientation while entering into the European Union market is especially seen in the case of entry forms on these markets. Analyzing the methods of Polish small and medium businesses entering on the European Union market, it can be additionally noticed the differences in internationalization progresses of these groups (table 2). The fundamental method of entering the European market for small and medium businesses is direct export, allowing to acquire experience of operation on the international market. Approximately half of the questioned businesses exports directly into the EU market (small businesses – 48 per cent, medium – 52 per cent, big – 42 per cent). This is an extremely significant fact proving that Polish businesses, including small and medium businesses, operating on the EU market want to control their sale regardless of taking greater risk than in the case of indirect export. This form enables gaining knowledge and experience in operation on foreign market. This element is especially important for businesses from SMB sector, since small and medium business as opposed to the large ones indicated in the research many years’ tradition of running the business on foreign markets. Gained experience on the international market may form the basis of international business development, including establishment of their subsidiaries or branches which may be seen in the case of these companies. The above mentioned research allows to conclude that every four company of SMB sector decided to invest in subsidiaries or branches on the EU territory or is sub-distributor of EU companies in terms of their long-term contracts.

Direct investments of Polish small and medium business most often cover the market which is the closest from the point of geography, that is German market. This tendency gives evidence of forming among the best functioning Polish businesses the need of entry on higher level of business internationalization. The traditional model of business internationalization starts from the export stage through licenses, joint venture and finishes with setting up own business abroad. Progressive process of globalization causes the increase number of cases infringing harmony of hitherto models of business internationalization. The example of such companies are enterprises operating on the strength of Internet, thanks to which even small business may in short-time operate around the world without forming the “physical” distribution canals abroad.

Generally speaking, less and less companies use the form of entry on the foreign markets through indirect export. It means that these companies want to directly control product and service sale on the international market. What is noticeable is the high rate of small and medium businesses establishing subsidiaries in the European Union countries. This is the highest level of business internationalization.

Conclusions

The ongoing changes in the attitude towards sources of advantage and foreign market entry modes and progressive but still noticeable companies shift in real capital and skills as shown in the research, shall be treated as a turn into the right direction and chance of competitiveness growth in Polish companies on the European Union market. It undermines prior thesis saying that small and medium businesses base their competitiveness entirely on traditional, easily-imitable competitive advantages, at least in the case of companies present on the European Union market. At the same time, it may be said that for this narrow sub-group the application of competitive advantage of higher order enables to compete in long-term prospects.

While taking actions connected with competing on common European market, Polish companies must first and foremost aim not only to gain profits but also to focus on company’s value growth and create values for customer. They shall also resign from building development policy based on cost leadership which in long-term does not allow to retain uniqueness of actions for the benefit of pursuit of own competitive advantage among reserve sources of competitiveness. While deciding on real capital development and own key skills, likewise it emerges in developed countries, Polish companies shall gain the possibility of not only maintaining but also improving their own competitiveness on the European market. In this case the most important role shall play the business capabilities of effective management and joining own resources and skills in respective configurations. The latter allows to create so called “key skills”, which are distinctive features of given company, but enabling for instance: application of unique and difficult to be implemented by competitors productive technology, introduction of innovative management systems, flexible responsiveness to changing market circumstances, performance of joint venture in cooperation with other companies, outsourcing application with simultaneous concentration on key business kind for enterprise, focus on high quality and its individuality or taking diversification actions with regard to create values for customer.
