Abstract:

The purpose of this article is to study the influence of industrial structure on the economic inequalities among counties at the less developed Yunnan Province in China. In the process of modernization, the country economy is the basic element of national economy and the ties of city with rural economic. Nowadays, Chinese economic operation of the prominent contradictions such as the regional inequality mostly is reflected in regional scale at countries. Therefore, it is necessary to discuss the county economic difference in order to coordinate regional development. Yunnan as a frontier, ethnic, mountainous and poor district, it is located in the western inland and one of the most imbalanced areas with regional development in China. After studied the literatures, we found the academia has not discussed the country economy from the perspective of industrial structure in Yunnan Province. So this article takes the shift share analysis and Industry decomposition of the Gini coefficient methods, based on the data of statistical yearbook, to analyze the evolution of industrial structure effecting county economic difference in Yunnan Province. The results show that: the economic disparities of counties affected by the deviation of industrial structure and competition greatly, the eastern counties of the industrial structure have a significant advantage, but the relative competitive advantage is weak, the western and southern counties have more competitive advantage, but less structural disadvantages than the eastern counties. In recent years, the eastern counties are dominant in the industrial structure, competitiveness, and the difference between the western and southern county are widened; the results from the decomposition of the Gini coefficient of industry indicate that the secondary industry is the leading factor causing the county economy difference. In addition, the tertiary industry contributes to increase county economic difference and its impacts on county economic difference has become increasingly prominent; also the change of industrial Gini coefficient decomposition reveals that the industry concentration effects to expand the county economy divergence but the structure effect can reduce the economic disparity. Finally, some well-directed policy recommendations and measures are provided to coordinate the county economic development.
