Research Of The Impact Of Producer Services Agglomeration On Yangtze River Delta Economic Growth

As the world economy transforms "industrial economy" to "service economy",the development of social division of labor and the improvement of professional level,service industry,especially the producer services separated from manufacturing industry by outsourcing form, has become an important power to promote national economic growth.The productive service industry has a strong industrial relevance and the height of the human and knowledge capital intensive, it plays an important role in improving regional economic competitiveness and the sustained and healthy economic development.Yangtze River Delta is one of the most developed area in China,productive service industry is developing rapidly in this area. Yangtze River Delta formed some agglomeration.However,by the literature review,I found that a majority of the study of the producer services agglomeration focused on the producer service industry agglomeration mechanism, affecting factors, measurement and the impact on manufacturing industry,few people study the impact on economic growth.By studying the impact of producer service industry agglomeration on the economic growth,I put forward some advice to promote the development of the productive service industry in Yangtze River Delta.The paper analyses the theory of producer services agglomeration impact on economic growth, on the basis of this, put forward the theoretical model of producer services agglomeration impact on economic growth.Secondly,I make a statistical analysis of the producer services agglomeration in Yangtze River Delta from the regional and industry level.finally,I combined with theoretical analysis,constructed the diversification index and specialization index,built the model of producer services agglomeration impact on the economic growth.The main conclusions of the research are that Shanghai,Nanjing and Hangzhou have a higher level of the producer service industry agglomeration than other cities in the Yangtze River Delta.From the industry point of view, leasing and business services,transportation,warehousing and the postal industry and the financial industry have a higher agglomeration level than others.Productive service agglomeration scale, diversification levels has a positive effect on economic growth, but the professional level have a negative effect on economic growth.Based on the above conclusions,I put forward some advice to promote the development of the productive service industry in Yangtze River Delta.
