|Other Abstract||With the transition of China's economy from industrial economy to service economy, producer services have developed rapidly and become more and more obvious. Moreover, manufacturing industry is often relatively developed in the areas where producer services gather. From the perspective of practical experience, the "two-wheel drive" development mode of modern service industry and manufacturing industry is a typical path of industrial development and transformation in developed regions or countries. Under this background, Chinese governments have issued relevant policies to encourage active development of producer services and promote the transformation of industrial structure to synergistic development of manufacturing and producer services. The Yangtze River delta is one of the important engines of China's economic development, which has the advantages of manufacturing industry agglomeration and the trend of producer service industry agglomeration is obvious, which forms the unique industrial agglomeration phenomenon and presents the unique regional characteristics. At the same time, the internal economic development of the Yangtze River delta is unbalanced, including economically developed cities such as Shanghai, Nanjing and other cities, as well as economically backward cities such as cities of Anhui. Under the background of supply-side structural reform, regional integration, it is necessary to research the economic effects of industry synergistic agglomeration of the Yangtze River delta. As an advanced stage of industrial agglomeration, industry synergistic agglomeration embodies the characteristics of technological and economic correlation between industries, and exerts the external effects of industrial agglomeration. Firstly, from the perspective of economic development, economic growth and industrial structure change are two aspects that constitute regional economic development. Economic growth reflects the expansion of the "quantity" of regional economic development and the change of the overall scale.The change of industrial structure reflects the evolution of the "quality" of regional economic development, reflects the change of the economic and technological relations between production organizations, which is also an important factor affecting output and benefits.Therefore, the most basic economic effects of industry synergistic agglomeration are industrial upgrading effect and economic growth effect. At the same time, the change of industrial structure and economic growth reflect the imbalance of regional economy, which causes regional income gap.The theory of spatial agglomeration points out that the externality of industrial agglomeration will have an impact on regional income, so industrial synergistic agglomeration not only affects industrial upgrading and economic growth, but also provides a new direction for alleviating regional income gap. Based on this, this paper explores the economic effects of synergistic agglomeration of manufacturing and producer services from three aspects: industrial upgrading, economic growth and regional income gap.|
This paper firstly sorts out the relevant theoretical basis of industrial synergistic agglomeration, laying a foundation for the analysis of the internal mechanism of industrial synergistic agglomeration acting on economic growth, industrial upgrading and regional income gap. Secondly, it measures and analyzes the industry synergistic agglomeration level in urban agglomeration of the Yangtze River delta from 2004 to 2016, laying a foundation for the empirical analysis of the economic effects of industrial collaborative agglomeration. Thirdly, taking the spatial econometric model and panel threshold regression model as the main research methods, the paper studies the economic growth effect, industrial upgrading effect and the impact on regional income gap of the industrial synergistic agglomeration. The main research conclusions are as follows: First, from the perspective of the change trend of industrial synergistic agglomeration index, the industrial agglomeration degree of manufacturing and producer services in urban agglomeration of the Yangtze River delta has a downward trend. The characteristics of producer services agglomeration in central cities and manufacturing agglomeration in surrounding cities are becoming more and more obvious. From the perspective of spatial pattern of industrial synergetic agglomeration, the high points of industrial synergetic agglomeration of urban agglomeration in the Yangtze River delta gradually shift from the east to the west. There is an obvious spatial positive correlation between industrial synergetic agglomeration, namely, the characteristics of high-value agglomeration and low-value agglomeration. Hefei, Xuancheng, Ma 'anshan and other western cities gradually show the characteristics of high-value agglomeration, while Yangzhou, Zhenjiang, Taizhou, Changzhou and other central cities show the characteristics of low-value agglomeration. Shanghai is in a high and low agglomeration area. Second, industrial synergy agglomeration effects the economic growth. 1. There is a spatial effect on the influence of industrial synergy agglomeration on economic growth of urban agglomeration. Industrial synergy agglomeration has a significant negative effect on local economic growth, while it has no significant negative effect on other cities. Overall, industrial synergy agglomeration has a negative inhibitory effect on economic growth. 2. Taking urban population, foreign investment proportion and employment density as threshold variables, it is found that there is threshold effect on the influence of industrial synergy agglomeration on economic growth. With the urban population growing, the influence of industrial synergy agglomeration changes from negative to positive; moderate proportion of foreign investment and employment density are beneficial to exert the positive effect of industrial cooperative agglomeration on economic growth. Third, industrial upgrading effect of industrial synergetic agglomeration. 1. There is a spatial effect on industrial upgrading of urban agglomeration in Yangtze River delta. The direct and indirect effects of industrial synergetic agglomeration on industrial upgrading are significantly positive and negative, indicating that inter-city industrial agglomeration is competitive, and industrial synergetic agglomeration in neighboring cities will inhibit industrial optimization and upgrading. 2. Taking industrial location entropy, urbanization level, government budget proportion and foreign investment proportion as threshold variables, it is found that there is threshold effect on the influence of industrial synergetic agglomeration on industrial upgrading. With the increase of industrial location entropy, urbanization level and government budget proportion, the influence of industrial synergy agglomeration changes from negative to positive; moderate proportion of foreign investment is beneficial to exert the positive effect of industrial synergy agglomeration on industrial upgrading. Fourth, the influence of industrial agglomeration on regional income gap. 1. There is a spatial effect on the influence of industrial synergetic agglomeration on regional income gap. The direct and indirect effects of synergetic agglomeration on income gap are significantly negative. Under the combined effects of direct and indirect effects, industrial synergetic agglomeration is conducive to narrowing regional income gap. From the perspective of sub-industry synergetic agglomeration, the direct and indirect effects of the synergetic agglomeration of transportation, warehousing and postal service, information transmission, computer service and software industry, scientific research, technical service, geological survey and manufacturing industry are significantly negative, while there are some differences in the degree of influence. The direct and indirect effects of synergetic agglomeration of business services and manufacturing are significantly positive. 2. Taking urban population, urbanization level, employment density as threshold variables, it is found that there is threshold effect on the influence of industrial collaborative agglomeration on regional income gap. With the expansion of city scale, urbanization level and employment density, the effect of industrial synergetic agglomeration turns from narrowing to widening, and the expansion trend is significant.
Based on the above research conclusions, this paper believes that it must reasonably promote the "two-wheel" driving strategy, transform the economic development mode, alleviate the crowding effect of industrial synergetic agglomeration, and transform the negative effect on economic growth in Yangtze river delta. At the same time, it must actively promote the Yangtze river delta regional integration, dredge spillover transmission path of industrial synergetic agglomeration, enhance the coordinating and driving role of central cities, accelerate industrial upgrading, narrow regional income gap, and give full play to the positive effect of industrial synergetic agglomeration.
