The Research On The Influence Factors Of MIX Effect And DIF Effect In China’s Urban Economic Growth

In the research of regional economy, regional disparity is always the hot point, and also the discussion of the formation of regional disparity, wherein, the economic structure of the regional disparity and the difference of competition ability is thought to be caused by the area difference main reason. However, China’s current economic growth resolve into the structural effect and competitive effect researches is still relatively few, and also lack of the researches which do some empirical research to search the course of economic growth. Therefore, the regional difference about city economy structural effect, competitive effect and influencing factors of research has a certain theoretical and practical significance.The full article is divided into five parts, first of all, from the topic background, summarizes the existing research on the regional disparity, economic structure, competition and the theory of Shift-Share analysis, form the focus of this paper.Secondly, according to the Shift-Share analysis method, using284prefecture-level city’s data from the year2003to2010, decomposed economic growth to structural effect and competitive effect, the results show that:A lot of Chinese city rely on the competitiveness growth or because of lack competitiveness to backward, structure effect led to the city economic growth has smaller differences.especially large scale city’s agglomeration economy has the most obvious advantages, the big city secondary, and small city’s development lags behind because of the elements of competitive disadvantage.Thirdly, look for the theoretical basis of economic structure and economic competitiveness, academia generally think that economic structure basically includes the industrial structure and the ownership structure, and the industry factor endowmentand the state of infrastructure is the three major influencing factors of competitiveness, provide the empirical theory support to the later chapters.Fourth, constructing static and dynamic econometric model to do empirical analysis through the employment of labor force growth function, we draw the conclusion:whether long-term or short-term, wage, k_gdp, revenue_share, gdp2_wage2, na_pop is the factors on the influence of the economic growth is the largest. Among this five factors, wage, k_gdp, gdp2_wage2, na_pop have a significant impact on both mix effect and dif effect. In addition, price, emp3_share, gdp2_share are also the mix effect influencing factors, revenue_share is also the dif effect factors.Finally, according to the Shift-Share decomposition and econometric model empirical results, summarizes the results and put forward some reasonable policy suggestions.
