An Empirical Analysis On The Effect Of Structure Change On Technology Efficiency Of Manufacturing Industry

As a symbol of the state's industrialization level, the manufacturing industry is an important national economic development growth points, it is not only related to the development of industrial modernization and the realization of economic and social development, but also to the basis of national security protection. Although, since the reform and opening policy, China's manufacturing industry has a rapid developed, But at the same time, the development of the manufacturing industry constrains by the carrying capacity of environment, the grim reality of situation urges that the china must change the original mode of development, explore a new path of development. The industrial structure plays an important role in the course of industrial development, changing to the industrial structure has become an effective way to industrial development. Therefore, combining the characteristics of the manufacturing industry, the author measure China's provinces and cities levels of structure changes. At the same time, constructing the technical efficiency model of manufacturing under environmental constraints and using the model calculates the China's provincial and municipal levels of technical efficiency, hoping to seek the relation between the structure changes and level of technical efficiency and finding a way to deal with the problems which happened in the development. That means this article has realistic and academic meanings.The aim of this paper which researches the effect of structure changes on technology efficiency of manufacturing industry is to find how changes in the structure to enhance the level of technical efficiency of China's manufacturing industry under the current environmental constraints and to seek the development of a "win-win" situation. On the basis of summarizing all the researches about structure changes and technical efficiency, the author firstly analyzes the reasons of structure changes and the structural changes of the manufacturing sector in China. Then author gives the conception of the technical efficiency and explores the intrinsic link between the structure changes and technical efficiency, then analyzes the way of effect of structure changes on technology efficiency of manufacturing industry.Subsequently, on the basis of the theory analysis, the author calculates the China's 29 provincial and municipal levels of technical efficiency and applies "DEA-TOBIT" model to analysis the effect of structure change on technology efficiency of manufacturing industry. The research shows that the structural convergence hinders the technical efficiency of manufacturing level. The increasing rate of structural changes and the enhancing status of regional aggregation promote the level of technical efficiency of the manufacturing industry.Finally, According to the conclusions of empirical research, the author gives some policy recommendations on how to promote the technical efficiency of the manufacturing industry from the perspective of the industrial structure.
