| National Economic and Technological Development Zone, is a product of China’s reform and opening up, which is set up to implement the reform and opening up policy. Between1984and1986, for the first time almost14countries economic and technological development zone have been set up.By2013,192state-level economic and technological development zone has been set up in total. After three decades of development, the National Economic and Technological Development Zone, has begun to take shape, and the amount of the main indicators of economic growth in the region is higher than the national average growth rate. By the end of2012, the development zone whose area is less than2%of the country’s total land has created12.8%of GDP (the "2013China Industrial Park continued development Blue Book"). In some areas, National Economic and Technological Development Zone has become an important driving force for local economic development and has become a veritable "growth pole". Industrial agglomeration is a kind of promoting regional economic development of emerging and effective spatial organization form. As an important phenomenon, industrial agglomeration not only has become a hot topic of economics, management, sociology and other fields in academia, but also advantages of industrial agglomeration in technology spillovers, economies of scale and other aspects have become increasingly prominent. Agglomeration effects arising in the course of promoting regional economic development in the role are increasingly obvious. At this stage our country always gets s clustering effect by the implementation of establishment of economic development zone industrial clustering strategy to promote the economic development of the region. But with "mushroom"-like appearance, the zones overlook the essential characteristics of the industrial zone cluster, making the phenomenon of "set without poly". Therefore, this article attempts to start from the Economic Development Zone, in the hope that through the empirical research of Qingdao economic development zone industrial agglomeration to reveal the influence of industrial agglomeration on economic growth and internal relations of the development of the economy, and make a decision for development China’s economic system reform pattern-economic and technological development zone, find a breakthrough point for the sustainable development of development zones in China, and from the perspective of industrial agglomeration development zone put forward the new ideas of transformation and upgrading.Qingdao Economic and Technological Development Zone which established under the supports of State Council approved at1984, relying on the convenient advantages of the port and a good resource, environmental advantages, gradually formed a household electronics, petrochemical, automobile manufacturing and other leading industries. In recent years, the three leading economic development zone industrial output value accounted for more than70%of the total industrial output value, becoming the important force to promote the development of Qingdao,even Hangdog district and economic. On the basis of combing study research literature at home and abroad, first of all, the theory of industrial agglomeration and industrial clustering effect has been elaborated; then the chemicals, household electronics, development status Qingdao Economic and Technological Development Zone petroleum automobile manufacturing industry agglomeration analyzed; exploit bit entropy industrial production areas, employment location quotient and integrated location quotient index estimates Qingdao Development Zone, petrochemical, electronic appliances, automobile manufacturing industry the degree of concentration; that building a place-based industry cluster analysis of industry growth theoretical framework with Cobb-Douglas production function approach analyze the impact on various industries industrial agglomeration of economic growth in Qingdao Development Zone; Then take the pulse function to estimate the economic growth of industrial agglomeration pulling utility Economic and Technological Development, and volatility affecting various industries industrial agglomeration effect on economic growth, the wave frequency empirical test. On this basis, draw a comprehensive empirical analysis conclusion and promote the further development of the industry in Qingdao Development Zone countermeasures and suggestions.Through the analysis, get conclusions as follow: a) Qingdao Development Zone, petrochemicals, household electronics, automobile manufacturing industry agglomeration of three has begun to appear. From the perspective of the extent of the three major industrial agglomeration, integrated location quotient of the petrochemical industry in Qingdao Development Zone0.12from1996to2002of0.42, it can be seen during the industrial agglomeration is not obvious, since2002; automobile manufacturing industry, industry cluster in the period from1996to2005, industry concentration has been at a relatively low value, but after2006, integrated car manufacturing industry location quotient increased quite obvious; appliances electronics industry is the highest of the three industry concentration degree, from1996to2012were integrated location quotient for a visible, Qingdao Development Zone agglomeration appliance electronics industry is the most obvious. b) Development of industrial agglomeration promote industry growth is very obvious. Petrochemical industry gathering of industry growth elasticity of0.25, which illustrate the level of specialization for each doubling in other conditions, such as labor and capital unchanged industrial output will increase by25%; household electronics industry gathering resilient to economic growth0.53, that illustrate the level of specialization for each doubling in other conditions, such as labor and capital unchanged industrial output will increase by53%; automobile manufacturing industry cluster to economic growth elasticity of0.39, which illustrate the level of specialization each doubling, under other conditions, such as labor and capital unchanged industrial output will increase by39%; explain industrial agglomeration has shown the important role of the industrial growth in the area of industrial development process, can indeed promote industrial agglomeration regional industrial growth. Possibility c) from the pulse analysis, household electronics industry gathering to GDP increased by the impact of fluctuations in the size of the impact of significant fluctuations, indicating that the impact of external shocks by other relatively large increase in household electronics industry agglomeration to have a role in promoting economic growth, basically only have an impact on every one, petrochemical industry, automobile manufacturing industry cluster development on economic growth has a significant role in promoting the development zone, and the impact with a lag, the impact of reach in the second year peak, and at about the fifth year reached steady state, pulse curve from the trend, the growth effects of Qingdao Economic and Technological Development Zone industrial Agglomeration will persist. |
