| In response to the 2008 financial crisis,the State Council issued the "ten major industries adjustment and revitalization plan" in the early spring of 2009,which has a positive impact on China’s industrial technological transformation,technological upgrading and structural adjustment.The product quality of an enterprise’s export shows whether the enterprise is competitive in the international market.At first,China’s export products are mainly labor-intensive,such as toys,clothing,etc.;in recent years,the technical content of China’s export products has been increasing.Therefore,this paper takes the ten industrial adjustment and revitalization plans as policy impact events,uses the micro data of prefecture level cities from 2006 to 2011,and uses the did double difference method in statal5 software to analyze the impact of industrial policies on the quality of export products.Firstly,based on the relevant literature,the sample data are merged and deleted.Then,this paper measures the explained variables,such as export product quality,control variables and intermediary variables,and makes an empirical analysis of the benchmark two-way fixed effect by using the double difference method.This paper makes a parallel trend test on the quality of export products between the control group and the control group from 2006 to 2009,and makes a group regression analysis according to the nature of enterprises and capital intensity.Finally,the paper selects financing constraints and government subsidies as two mediating variables to build the model and test the mediating mechanism.The results show that:1.The introduction of industrial policies in the ten industry revitalization plan promotes the improvement of the quality of export products.2.In order to ensure the robustness and reliability of the regression results,parallel trend,eliminating the interference of financial crisis events and replacing variables are used to verify the results.The results show that the conclusion that the quality of export products of the top ten industries is improved is still valid.3.In order to further explore the specific impact,this paper tests the heterogeneity according to the different grouping regression of enterprise nature,trade mode and capital intensity,and finds that processing trade enterprises,Hong Kong,Macao and Taiwan funded enterprises and capital-intensive enterprises are affected by industrial policies,and the quality of export products is improved more significantly.Compared with labor-intensive enterprises,capital intensive enterprises export more products The improvement of quality is more significant.4.This paper analyzes the mechanism of the industrial policy of the ten industrial revitalization plan,and finds that the industrial policy can improve the enterprise financing environment and provide subsidies to enable enterprises to have enough funds to carry out production,operation and R&D activities,so as to improve the quality of export products. |
