The Impact of Free Trade Zone Establishment on the Agglomeration of High-end Service Industry in Pilot Cities

Using 286 prefecture level cities data and the DID method from 2009 to 2017 in China,the establishment of the Free Trade Zone is regarded as a quasi natural experiment,and its policy impact on high-end service industry agglomeration in pilot cities is evaluated.The results show that:(1)the establishment of the Free Trade Zone has a significant positive impact on the high-end service industry specialization agglomeration,but it has no obvious effect on the diversification agglomeration;(2)the establishment of the Free Trade Zone promotes the high-end service industry specialization agglomeration,which has a trend of increasing over time in the short term;(3)the heterogeneity analysis shows that the establishment of the Free Trade Zone only significantly improves the concentration of high-end service industry specialization in eastern pilot cities and first-class pilot cities.The establishment of the Free Trade Zone has not a significant effect on the diversification of high-end service industries in pilot cities in different regions and pilot cities of different levels.
