Creation of economic potential depends on many factors, including the tax ones. One of the tasks of the tax system is, above all, to stimulate investments and consumption, as well as to influent the activity of business entities. Enterprises through their activity contribute to the development of the economic potential of the area. Tax receipts, eg from: personal income tax, corporate income tax, goods and services tax, allow to assess the economic potential in a given area. The aim of the article is to analyze the literature on the subject in terms of development of the economic potential of regions and views on the impact of taxes on local economies. In relation to the aforementioned issues, data on tax revenues (CIT, VAT) were collected in 2012-2016 in the Lubuskie and Dolnośląskie voivodships, and analyzed. In article were used research metod - statistical inference based on the analysis of statistical data The study included the use of the following statistical indicators: income from legal persons, from goods and services in individual tax offices of the Śląskie and Dolnośląskie voivodships for one taxpayer in PLN; the dynamics of income tax receipts from individuals, from legal persons and from goods and services. Based on the research, appropriate conclusions were made. Economic development is concentrated in large poviats. Key words tax revenue, corporate income tax, value added tax JEL classification: P43 1. Introduction The functioning of the economy is closely related to business entities whose activity directly affects economic development. From the point of view of economic management, it is very important to analyze economic development for the whole country as well as in the scale of the regional economy, for example in a given voivodship. The article presents to cover the areas of southern Poland The purpose of this article is to analyze and evaluate the economic potential in the Śląskie Voivodeship and Dolnośląskie in 2012-2016 through the prism of selected tax receipts. As part of the research, a research hypothesis was formulated that the economic potential in the Śląskie and Dolnośląskie voivodeships in the years 2012-2016 was spatially diversified. The following research methods were used in the article: literature studies in the field of taxation as an economic policy tool, and statistical inference based on the analysis of statistical data. Sborník příspěvků XXI. mezinárodní kolokvium o regionálních vědách Kurdějov 13.–15. 6. 2018 263 The complexity of the issue of economic potential required during the study of the application of many measures to its evaluation. The following indicators were developed for the needs of the analysis: 1) income from corporate income tax in individual tax offices of the Śląskie and Dolnośląskie voivodships (in PLN); 2) income from tax on goods and services in individual tax offices of the Śląskie and Dolnośląskie voivodships (in PLN); 3) dynamics of income tax receipts from legal persons in individual tax offices; 4) dynamics of receipts of tax on goods and services in individual tax offices. Data for analysis was obtained from the Tax Administration Chamber in Katowice and the Tax Administration Chamber in Wrocław. 2. Taxes as a factor of economic development Taxes in the economy are an economic and legal category and they help to finance public and social goods. According to Joseph E. Stiglitz, taxes, mainly income-related, affect the way the economy operates through a determined impact on the allocation of resources and the inclination to bear the risk (Stiglitz, 2013, p. 555). The tax system is to perform certain functions in a given economic system. By its construction, the state can achieve various economic goals. Providing funds for the implementation of state policy is the essence of the overriding fiscal function of taxes. Taxes are also fillednon-fiscal functions that are implemented through the structure of the tax system and the level of taxation. Many authors believe that they are a factor in the economic development of each country (Grycuk, 2010, pp. 1-2). More and more often different indicators are used to make the diagnosis of the economy, apart from the basic gross domestic product. Economists are looking for newer solutions that would reflect the essence of the state of a given economy, for example national and local. In 2008, the Commission for Measuring Economic Performance and Social Development, which was chaired by the Nobel Prize winner Joseph E. Stiglitz, began operations in France. The Commission has developed a position that there is a need to modernize the system of measuring economic activity, so that it better reflects changes in the functioning of modern economies. Today, you should not use the gross domestic product alone when assessing a given economy, but extend it to other factors, for exampleabout taxes (Kisiel, Marks-Bielska [ed.], 2013, p. 44). In the literature on the subject, there is the opinion that low tax revenues obtained in a given area cause that the economic development of these areas will be low (Włudyka, Smaga, 2012, p. 193). In the subject literature, we meet many definitions of economic development. The authors of the new Encyclopedia of PWN through economic development understand the quantitative and structural changes in the national economy that are the result of economic growth (Sztaba, 2004). In turn, in the Encyclopedia Britannica we find the definition that economic development is a process involving quantitative and qualitative changes, as a result of which primitive low income economies are transformed into economies with a higher level of income level (Myint, Krueger, 2011). Economists present many approaches to the problem of building measures of economic development as well as socio-economic development. The discussion usually focuses not on the problem of selecting the best measures, but on adopting a synthetic measure. Studies scientifically most often consider the size of national income per capita as such (McGranahan, 1972, p. 16). According to Katarzyna Czaplicka, in order for economic development to take place, it is necessary not only to change quantitatively (economic growth), but also to transform the quality of the economy. Thus, economic development determines the overall changes taking place in the long-term economy (Bąkiewicz, Czaplicka, 2011, p. 77). In turn, Michał Gabriel Woźniak admits that in order to talk about economic development, it is necessary to analyze qualitative changes in the socio-economic structure of the country in addition to quantitative changes (Woźniak, 2008). Hendrik van den Berg also spoke about economic development, saying that it is a process of constant change (Van den Berg, 2017, p. 15) Research on economic development was conducted by M. KabirHassan, Benito Sanchez, and Jung-SukYu. They found positive links between financial development and economic growth in developing countries (Kabir Hassan, Sanchez, SukYu, 2011, p. 90). The local economic development will be discussed in the pages of this article, which will concern the area of the Śląskie and Dolnośląskie Voivodships.

Diversification of the economic potential of the Dolnośląskie voivodship in the aspect of tax revenues The Dolnośląskie Voivodship located in the south of Poland covers an area of 19947 km2. The area of the voivodship gathers 2,903,000 people. The voivodship consists of 26 poviats and 4 cities with poviat rights. There are 87 cities in the Dolnośląskie Voivodship. In the years 2002-2016, the number of inhabitants decreased by 0.3%. The average age of residents is 42.0 years and is comparable to the average age of inhabitants of all of Poland. 62.0% of the inhabitants of Dolnośląskie Voivodship are in working age, 16.8% in the pre-working age, and 21.2% of residents are in the post-working age. Unemployment registered in Dolnośląskie amounted to 7.3% in 2016 (8.2% in women and 6.5% in men). This is much less than the unemployment rate for Poland. The average gross monthly salary in Dolnośląskie amounts to PLN 4,385.84, which corresponds to 102.20% of the average monthly gross wage in Poland. 10.6% of professionally active inhabitants of the Lower Silesian Voivodship work in the agricultural sector (agriculture, forestry, hunting and fishing), 32.4% in industry and construction, and 19.8% in the service sector (trade, vehicle repair, transport, accommodation and gastronomy, information and communication) and 4.1% work in the financial sector (financial and insurance activities, real estate services) [http://www.polskawliczbach.pl/dolnoslaskie#ixzz5AQCRhqM5] In Wrocław, there are several tax offices that serve taxpayers from the city's territory and, additionally, the Wrocław poviat. The area of the Silesian Tax Office supports large taxpayers, ie tax capital groups, banks, insurance companies, entities operating under the provisions of the Act on Trading in Financial Instruments and provisions on investment funds, pension funds, branches or representative offices of foreign enterprises and other business entities whose annual turnover exceeds PLN 5 million.

It should be emphasized that in smaller tax offices, where other entrepreneurs operate, there is also a large economic potential, as evidenced by the amount of VAT tax revenues per taxpayer (over PLN 10,000). This applies to, among others, Oleśnica, Głogów, Legnica, Oława, Środa Śląska (in 2014-2016), Wrocław, Ząbkowice Śląskie (years 2015-2016), Zgorzelec (years 2015-2016), and Polkowice (years 2015-2016). In some years of the analyzed period, the economic potential of selected poviats was much larger than the average of the voivodship. This concerned, among others, the following tax offices: Polkowice (2015-2016), Wrocław Psie Pole (2012-2015), Wrocław Stare Miasto (2012, 2013, 2014). 4. Diversification of economic potential in the Silesia Voivodeship Silesia is located in the southern part of Poland and covers an area of 12.333 km2. The area of the province is 4.559 thousand residents. The voivodship consists of 17 poviats and 19 cities with poviat rights. In total, there are 71 cities in the Śląskie Voivodeship. In the years 2002-2016, the number of inhabitants decreased by 3.6%. The average age of residents is 42.2 years. Unemployment registered in Silesia was 6.6% in 2016 (7.8% among women and 5.5% among men). This is much less than the unemployment rate for Poland. The average gross monthly salary in Silesia is PLN 4,295.29, which corresponds to 100.10% of the average monthly gross wage in Poland. 7.8% of professionally active Silesian residents work in the agricultural sector (agriculture, forestry, hunting and fishing), 38.2% in industry and construction, and 20.1% in the service sector (trade, vehicle repair, transport, accommodation and catering , information and communication) and 3.6% work in the financial sector (financial and insurance activities, real estate services). In the entire Silesian voivodeship, 37 tax offices deal with tax collection.

In the analyzed period the best year was 2014, because the highest tax revenues were recorded then. In two cases (2015 and 2016), the taxpayer recorded a negative impact on US Tychy, which indicates that the economic potential of these areas also developed. Despite the fact that during this period, tax offices paid more for VAT than recorded revenues, this situation testifies to the development of foreign trade. If there are VAT refunds, first of all, the sale takes place with 0% VAT and VAT refund is applied.

Sborník příspěvků XXI. mezinárodní kolokvium o regionálních vědách Kurdějov 13.–15. 6. 2018 269 Conclusions The analysis carried out with the use of synthetic indicators has highlighted many situations indicating the good development direction of individual regions of the Śląskie and Dolnośląskie Voivodships. In addition, it allowed to formulate a few conclusions regarding economic development: 1) The phenomenon of economic development does not occur evenly in the region and is strongly conditioned by the existence of entities paying taxes or using the refund of tax on goods and services on account of sales outside the Republic of Poland. 2) Development is concentrated in large poviats, but some positive trends in much smaller poviats can also be noticed, 3) Lack of large enterprises in poviats located on the outskirts of the voivodship (which illustrates the income from corporate income tax) causes that these areas are characterized by much smaller development than the areas located in the central parts of the voivodship. In order to accelerate the economic development of the poviats indicated during the study as the least economically developed, it would be necessary to improve and develop infrastructure that would help bring new entrepreneurs to this area or stimulated the development of existing businesses.
