Evaluation Of Implementation Effect Of Western Development Policy Based On Multi-stage DID

After the implementation of the western development strategy,the economic and social development of the western region has made historic achievements,but the unbalanced and insufficient development of the western region is still prominent.In order to ensure the consistency of the implementation of the follow-up western development strategy,On May17,2020,the CPC Central Committee and the State Council proposed to continue to strengthen the promotion of the western development and form a new pattern.The central economic conference held at the end of2021 also clearly pointed out that we should continue to implement major regional strategies and promote coordinated regional development.Therefore,it is particularly important to evaluate the implementation effect of the past western development policy,which can not only provide some consideration for the improvement of the subsequent western development policy,but also provide reference for the implementation of other regional economic policies.Based on the western development,this paper first arranges and summarizes the relevant literature of the western development,and determines the research content of the western development policy on the basis of the existing research in the past.Secondly,it reviews the policies promulgated in the 20 years of the implementation of the western development,and analyzes the achievements of the western region under the background of the western development policy.Thirdly,in order to analyze the net effect of the western development policy,based on the panel data of 31 provinces and cities in China from 1990 to 2020,the multi-stage did model is used to peel off the influencing factors of other policies on the western region,and evaluate the net effect of the western region and its surrounding areas under the western development policy from the perspectives of economic growth,industrial structure and disposable income.Finally,Analyze the possible problems from the implementation of the western development policy to the middle stage of rapid development,and put forward relevant suggestions according to the research results.After research,the following conclusions are drawn: first,the western development can effectively promote the economic growth of the western region and the increase of the per capita disposable income of urban residents,but it does not promote the optimization of industrial structure.Second,the western development policy has a lag effect.Third,although the western development policy can improve the development level of the western region,the income gap between the East and the west is still widening.Fourth,the western development policy has a negative effect on the surrounding areas of the west,that is,there is a siphon effect.According to the above research results,the following suggestions are put forward to further promote the smooth implementation of the Western Development: first,increase investment in infrastructure construction to ensure the economic environment of the western region.Secondly,strengthen the trade cooperation between the western region and other countries,introduce foreign capital and promote the optimization of industrial structure.Thirdly,increase the investment in education in the western region,improve the quality of labor force and turn knowledge into productivity.Finally,we will strengthen tax reduction and fee reduction,attract enterprises to settle in,and encourage high-end technological innovation.
