Research on the path of railway infrastructure's impact on technological progress - Empirical analysis based on Chinese Provincial Panel Data

摘要

Based on China's provincial panel data for 2000-2016 years, this paper uses the Malmquist index method to measure China's technology progress index. The direct and indirect effects of railway infrastructure on technological progress are measured by the panel data analysis model with cross terms. The results show that: Although slower technological progress is the main reason to hinder China's TFP growth, this problem is improving significantly in recent years. Obviously, railway infrastructure has a direct effect on technological progress. Technology import is the main way of technological progress in China, and international trade is the main way of technology import. The smaller the density of railway infrastructure is, the more obvious the impact of international trade on technological progress is.
