研发投入、技术创新对产业结构升级的影响研究 ——基于全国30个省级面板数据的实证分析

Research on the Impact of R&D Input and Technological Innovation on the Industrial Structure Upgrading: Empirical Analysis Based on Panel Data of 30 Provinces and Municipalities Across

摘要:

基于2005—2018年全国30个省市区（不包括港澳台和西藏）的面板数据，运用广义最小二乘估计（GLS）和Bootstrap中介效应检验方法研究研发投入、技术创新对产业结构升级的影响。实证结果表明，研发投入能显著促进产业结构升级，技术创新在研发投入对产业结构升级影响中发挥显著的中介效应，但中介效应只有14.43%，仍有很大的提升空间。根据实证研究结果，提出推动技术创新和产业结构升级的政策建议。

Abstract:

Based on the panel data of 30 provinces and municipalities (excluding Hong Kong, Macao, Taiwan and Tibet) from 2005 to 2018, the generalized least square estimation (GLS) and Bootstrap intermediary effect test methods are used to study the impact of R&D input and technological innovation on the upgrading of industrial structure. The empirical results show that R&D input can significantly promote the upgrading of industrial structure. Technological innovation plays a significant intermediary effect in the impact of R&D input on industrial structure upgrading, but the intermediary effect is only 14.43%, and there is still a lot of room for improvement. Based on the results of empirical research, policy recommendations to promote technological innovation and industrial structure upgrading are put forward.
