Abstract: 1) Based on the background of the western development drive policy for 20 years, this paper identifies the net effect of this policy on the regional opening from the perspectives of opening to the outside world and opening to the domestic, and further evaluates and ranks the western provinces' opening to the outside world from the macro perspective, trying to grasp the general situation of the western region's internal and external development.(2) This paper analyzes the net effect of the policy by the method of DID (Differences-in-Differences).After that, a series of robustness tests are carried out, including parallel trend, counterfactual, substitution variable and so on.Entropy method is used in the comprehensive evaluation of provinces.(3) Through regression analysis, this paper finds that the implementation of the western development drive policy has an inhibitory effect on the opening to the outside world in western region, while has a positive role in promoting the opening to domestic.Further research finds that the cause of this result may be the "squeeze effect" of capital.In addition, Sichuan, Chongqing and other regions ranked higher in opening up in the western region, while Qinghai, Ningxia ranked lower.
