| Research Objectives：This paper is to study the influence and mechanism of integration of the Yangtze River Economic Belt on the R&D efficiency of high-tech industry. Research Methods: Taking the provinces of the Yangtze River Economic Belt as the research object, it uses the model of the ideal decision-making unit cross-efficiency to measure the R&D efficiency of high-tech industry. Then by constructing DID model and panel threshold model, it tests the relationship between the integrated development of the Yangtze River Economic Belt and the R&D efficiency of high-tech industry. Research Findings: The integration of the Yangtze River Economic Belt has a significant role in promoting the R&D efficiency of high-tech industries. Further analysis finds that the integration on the R&D efficiency of high-tech industries is related to regional heterogeneity, that is, the promotion of midstream area and downstream area is stronger. In terms of the mechanism, there is a double threshold based on R&D intensity between the integration of the Yangtze River Economic Belt and the R&D efficiency of high-tech industry, and it presents a non-linear inverted “U” type characteristics. Research Innovations: Combine the development strategy of the Yangtze River Economic Belt and high-tech industry, and analyze effects of integration on the R&D efficiency of high-tech industry. Research Value: Integration of the Yangtze River Economic Belt is conducive to upgrading high-tech industry‘s R&D efficiency. Providing references and suggestions for the innovation and development of China‘s high-tech industry in view of regional integration. |
