The Interactive Correlation Effect Of Producer Services And Manufacturing Research In Triangle Of Central China

Since later 20 th century, there is a general trend of transition that the global industrial structure transfer from the "industrial economy" to "service economy".Within the service industry, the producer services are developing quickly, it’s percentage increase and become the dominant force in the service economy development. Producer services have promoted the world service industry industrial structure upgrade. On the other hand, manufacturing value-chain trend has become increasingly obvious and there is an increasing demand for producer services.Otherwise, the growth of producer services sector also depends on the increase of intermediate input manufacturing sector.Triangle of Central China is in the middle of industrialization, Manufacturing of high growth at the same time presents the trend of the service. The productive service industry has developed rapidly in recent years, But the disadvantages of manufacturing development makes it lack of competitiveness across the country and even in the international market, especially the interactive effect of the manufacturing industry and productive service industry is insufficient seriously restricts the efficient development of both. Through the input and output method of producer services and manufacturing industry association analysis found that about Triangle of Central China, the relationships between manufacturing industry and producer services function is insufficient, the manufacturing level is lower. The producer services especially reflect the level of service industry development of the financial sector, business services,information technology and software industry, scientific research and comprehensive technical services and other industries to a serious shortage of demand; At the same time, the low level of producer services also can’t satisfy the demand in the middle of the manufacturing. Both restrict each other, led to the transformation and upgrading of traditional manufacturing is more difficult and restricted the rapid development ofproducer services. After both correlation analysis, and through the composition of Triangle of Central China’s three big city circle, thus the wuhan city circle, Ring of changsha-zhuzhou-xiangtan urban agglomeration and Poyang lake urban agglomeration. Through building time series model and making studies the interaction between producer services and manufacturing sector as a whole effect, the results show that the wuhan city circle, Ring of changsha-zhuzhou-xiangtan urban agglomeration obvious the interactive effect of the producer services and manufacturing, and manufacturing of producer services is stronger than the influence of producer services on manufacturing; Poyang lake urban agglomeration manufacturing industry and producer services plays weaker role in promoting each other.Based on the above research of Triangle of Central China reflects the characteristics and problems in the development of producer services and manufacturing, Then put forward to promote the positive interactive between the producer services and manufacturing development countermeasures and suggestions from three aspects, from the adjustment of industrial structure, the transformation of the mode of manufacturing development and regional innovation and coordinated development.
