Will Foreign Direct Investment Affect the Productivity of Enterprises? ----Based on PSM+DID Method

摘要

Is OFDI able to improve the productivity of enterprises? This paper uses the data of Industrial Enterprise Database from 2000 to 2007 to conduct empirical tests. Based on the theory of Propensity Score Matching (PSM) and Double-Differences (DID), this paper constructs an econometric model and explores the impact of OFDI on the productivity of Chinese industrial enterprise based on overcoming endogenous problems. The results show that OFDI has a positive effect on the productivity of enterprises. On the basis of the basic regression, the paper also obtained the control group samples at the ratio of 1:2, 1:3, 1:4 and 1:5 to obtain the control sample, which proved the robustness of the conclusion. These findings provide a new dimension of interpretation for verifying the need for China to implement the "going-out" policy and enhancing the competitiveness of Chinese enterprises under the new economic normal.
