Does Domestic Trade Affect Regional Industrial Competitiveness?:Evidence from Urban Panel Data of Anhui Province
The theory of competitive advantage was applied to analyze the mechanism of the impact of domes-tic trade on regional industrial competitiveness,an overall regression model and instrumental variable model were constructed.After applying multiple estimation strategies,the regression results show that domestic trade has a significant positive promoting effect on the improvement of regional industrial competitiveness,and its importance is relatively higher.This result is still valid considering endogeneity and has passed multiple ro-bustness tests.Further group analysis results show that the positive promotion effect has significant heteroge-neity in enterprise nature and geographical location,the average estimated effect of the non-state-owned en-terprises and the group in southern Anhui is relatively high.In the new stage of development,Anhui Province should give priority to promoting the improvement of domestic trade level,and highlight the relative impor-tance of non-state-owned enterprises and the southern region in enhancing Anhui's industrial competitive-ness,while accelerating the formation of a high-quality regional economic layout tailored to local conditions.
