Study On The Upgrading Of High And New Technology Industry Cluster From The Perspective Of Value Chain

After the reform and opening up,the development of China's economy has been integrated into the process of economic globalization,China's economy increasingly close in touch with the world economy,and become one important part of it.Globalization and trade liberalization promote and accelerate the low-cost free flow of economic factors in the global scope. As the leading industry of knowledge economy, the development level of high and new technology industry determines the competitiveness of the country and the region. China's high technology industry cluster has begun to take shape, many clusters are in different ways through the value chain to merged into the global industry network, but in the international division of labor, the high and new technology industry clusters in our country are still in the low end, in order to promote the development of the industry and the level of regional economy, and promote the sustainable development of high-tech industrial clusters to take share the benefits and opportunities that globalization bring about is increasingly urgent.This paper studies the upgrading of high-tech industrial clusters from the perspective of value chain.On the basis of the theory of global value chain and industrial cluster,according to the different angles of cluster value chain,from four aspects that conclude the high technology industrial cluster internal driving force, cluster growth impetus, cluster spillovers impetus and external driving force to research the industrial cluster upgrade power,select the dynamic evaluation index of the upgrading of high-tech industrial clusters, and build a dynamic evaluation model;Taking the software industry cluster in Xi'an high tech zone as an example and using the AHP method to determine index weight and performed three-level fuzzy comprehensive evaluation, according to the result of fuzzy comprehensive evaluation, the influence factors are classified and analyzed by using primary and secondary factor analysis method.Based on theoretical and empirical research to propose upgrading strategy of the perspective of value chain of high-tech industry cluster.It is hoped that the research of this paper can be used for reference to promote the high-tech industry cluster constantly upgrading and regional economic development.
