| With the continuous progress of the industrialization process,the status of hightech manufacturing industry in the national economy is increasing,and its level of development marks the economic strength and international competitiveness of a country or region.The productive service industry,which is born out of the manufacturing industry,has a close relationship with the manufacturing industry.It serves as an intermediate investment in the manufacturing industry,which has reduced the internal production cost of the manufacturing industry and promoted the scale of production and realized the product value chain On the rise,thereby increasing its production efficiency.Compared with the developed countries,the development level of China's productive service industry is still insufficient,its role in promoting the efficiency of high-tech manufacturing is not clear,and the current scholars on the impact of producer services on the impact of high-tech manufacturing efficiency is still Rare.Therefore,it is of great significance to explore the effect of productive service industry on the efficiency of high-tech manufacturing industry.Therefore,this paper first combs the relationship between the productive service industry and the high-tech manufacturing industry and the related literature and theory of the efficiency of the high-tech manufacturing industry in the productive service industry.Then,it expounds the influence of the productive service industry on the high-tech manufacturing And then analyzes the present situation of the development of productive service industry and high-tech manufacturing industry in China.On this basis,this paper adopts the panel data of 30 provinces and cities in China from 2005 to 2015,and uses the spatial panel metrology model(SEM and SAR),and constructs four spatial weight matrices of geography adjacency and distance,economic distance and human capital,This paper analyzes the influence of productive service industry on the efficiency of high-tech manufacturing industry from three different perspectives at the national level,time level and regional level.Finally,according to the research of this paper,how to improve the production efficiency of China's high-tech manufacturing industry put forward relevant countermeasures and suggestions.In this paper,through theoretical and empirical research,the following main conclusions are drawn:(1)The productive service industry can not only improve the efficiency of the high-tech manufacturing industry in the region,but also enhance the height of its neighboring areas and their economic and social conditions through spatial spillover Technical manufacturing efficiency,and the spillover effects of high-tech manufacturing efficiency occur more in areas with similar economic and social characteristics.(2)the relationship between producer services and the efficiency of high-tech manufacturing industry shows the characteristics of dynamic evolution.(3)The effect of the productive service industry in each region on the efficiency of high-tech manufacturing industry has some differences.The Bohai Sea and the northeastern region of the lifting effect was significantly higher than other regions,while the Northwest region to enhance the role of the smallest.In addition,the spatial spillover effect in the central region is not significant.(4)The combination of foreign direct investment,R&D intensity,high-tech manufacturing industry,traffic environment and knowledge spillover environment have significantly promoted the improvement of the efficiency of high-tech manufacturing industry,and only negative effects in individual regional samples.Significantly. |
