The Research On Innovation-induced Mechanism Of Leading High-Tech Industries' Growth

Leading high-tech industries refer to high-tech industries with high growing capability, high innovation ratio and high industrial linkage which play breakthrough leading role in economic growth and arouse the concern from governments and theoretical field gradually. This thesis takes innovation as the endogenous variable and reveals the growth mechanism of the leading high-tech industries, which are of both theoretical and practical significance to induce healthy and rapid growth of leading high-tech industries, to drive economic growing and upgrade the industrial structure.There are 5 chapters in this thesis. The first chapter is the introduction. In the 2^nd chapter it takes innovation as the important endogenous variables which can induce the growth of leading high-tech industries based on the Schumpeter's growth theory, endogenous growth theory and the theory of firm growth. In chapter 3, it sets up the variables' constructive evaluation model of leading high-tech industries' growth on the base of Solow's exogenous growth model and Romer's endogenous growth model. Using the data of the 9 leading high-tech industries from 1995-2006, it conducts an empirical analysis on the model. In chapter 4, it reveals the path that innovation induces the growth of leading high-tech industries by using the SEM method. The 5^th chapter is the conclusion.This thesis concludes that innovation is not the direct driving factor to the growth of leading high-tech industries, but it is the endogenous induce factor and it works through two paths by enhancing industrial quality. Through carrying a regression analysis on the variables' constructive evaluation model, it shows that capital and labor have greater construction to the growth of the leading high-tech industries than innovation, which is both inconsistent to the classical growth theory and be coincident with the "Solow Paradox" emerged in 90's. Using SEM to conduct an empirical analysis on the growth path of leading high-tech industries induced by innovation, it shows that innovation promote the growth of leading high-tech industries through two paths by enhancing industrial quality, innovation input works through innovation output and industrial quality, innovation output works through industrial quality. The industrial quality is the direct driving power factor and the intermediate variable which can enlarge and strengthen innovation's effect on the industrial growth, and it is just the reason of the inconsistency between theoretical expecting and empirical outcome. Based on the conclusions this thesis suggests that we must increase the innovation input, improve the resource-using efficiency, coordinate between innovation input, innovation output and industrial quality to make leading high-tech industries growth sustainable and healthy; we must enhance the industrial quality, promote technical progress by innovation, improve the total factor productivity to enhance the industrial's international competitiveness.
