| At present,The main contradiction in China is the a conflict between unbalanced and inadequate development on the one side and the people’s ever-growing desire for a better life on the other.The urban agglomeration strategy can effectively improve the imbalanc problem and promote regional economic growth.The strategy of urban agglomeration has become an important strategy in China and a booster for the overall development of Chinese economy.In 2006,the government of Hunan officially implements the strategy of the urban agglomeration around Changsha-Zhuzhou-Xiangtan.This strategy has important implications.The important purpose of the urban agglomeration is to promote the coordinated development among cities,and regional economic growth,thus,the strategy can drive the economic growth of the entire Hunan Province.In the central part,the urban agglomeration plays an important role in the whole region,so it is necessary to accelerate the construction of the urban agglomeration around the Changsha-Zhuzhou-Xiangtan.Therefore,it is necessary to explore the relationship between the strategy of the urban agglomeration and the economic development from the theoretical and empirical perspectives,as well as the path through which this close relationship is carried out.In view of this,summarize the relevant literature,and combined with the relevant theories of urban agglomeration and economic growth,to sort out the relationship between the urban agglomeration around Changsha-Zhuzhou-Xiangtan and economic growth,it is believed that the former affects the latter through three paths,improving the level of financial development,increasing the construction of transportation facilities and promoting the upgrading of industrial structure.Using the panel data of14 cities in Hunan Province from 1999 to 2020,and using the difference-in-difference(DID)method to analyze the effect of the implementation of the strategy of the urban agglomeration around Changsha-Zhuzhou-Xiangtan on economic growth.The research results show that a positive relationship between the urban agglomeration and economic growth,so the urban agglomeration can promote economic growth.Next,in order to ensure that the assumption of using the differences-in-differences method is met,a parallel trend test is performed on the treatment group and the control group,and the results show that the two group have the same trend before and after the policy is implemented.In order to avoid the endogeneity problem,carring out the endogeneity test,and uses the explained variable with a lag of one period as the instrumental variable for regression to solve the endogeneity problem.Then,the analysis of the impact mechanism is carried out,and it is concluded that the urban agglomeration strategy has an impact on the level of financial development,the construction of transportation facilities and the industrial structure.Improving the level of financial development,improving the construction of transportation facilities and promoting the upgrading of industrial structure will promote economic growth.Finally,this paper uses a counterfactual test to conduct robustness tests,and the test results show that the above empirical results are robust.According to the above research conclusions,recommendations are made from the following three aspects.First,continue to promote the construction of the urban agglomeration around Changsha Zhuzhou-Xiangtan;second,promote the development of the financial market and build a unified financial service system.Third,improve the construction of transportation infrastructure and form a more complete transportation network;fourth,establish a rational industrial division of labor system to give play to the relative advantages of the city.The innovation of this paper is taking the urban agglomeration around Changsha-Zhuzhou-Xiangtan as the research object,deeply discussing its impact on regional economic growth,and in-depth analysis of the impact mechanism,using empirical evidence to test the impact mechanism. |
