The Effect of Technology Transfer Efficiency of Policies for Coordinated Development in the Beijing Tianjin Hebei Region: Evaluate by Using a Difference-in-differences Model

Abstract

This paper uses the DID model to explore the impact of the implementation of the Beijing-Tianjin-Hebei coordinated development in 2014 on the efficiency of technology transfer in China. A comparative study was selected for the 6 years before and 5 years after the implementation of the policy. The technology transfer efficiency is calculated by the CCR and SBM of the DEA model. The scale of urban development and the financial capacity of the government are the control variables, which proves that the policy can improve the efficiency of regional technology transfer. The model passed parallel trend test and placebo test.
