Abstract:The Fifth Plenary Session of the Eighteen Central Committee proposed five new development concepts, which put innovation on the first place and also addressed the key role of technology innovation. The promotion of Jing-Jin-Ji integration needs to upgraded adjust industrial structure, and technology will provide strong internal power. This paper developed the theoretical framework of technology innovation on industrial structure upgrading adjustment, which revealed the importance of technology innovation. Thus, this paper used 1985-2016 panel data of Jing-Jin-Ji to conduct empirical analysis. The results indicated that there were positive relationships between technology innovation and industrial upgrading adjustment in Jing-Jin-Ji area. The increase in education and science level would accelerate industrial structure upgrading adjustment. In addition, the promotion from science level in augmenting the productivity of service industry was more significant. Hence, the expenditure on education and R&A should be increased to improve the quality of human capital, and then to promote Jing-Jin-Ji industrial structure upgrading adjustment by technology innovation. Secondly, the institutional innovation was positive to technology innovation, which would provide better internal power and external environment. Finally, technology innovation could be accelerated by supply-side reform, and future promoted Jing-Jin-Ji industrial structure upgrading adjustment.
