Abstract:     Since 2010, the output value of China′s manufacturing industry has remained the largest in the world, and its industrial innovation capacity has been significantly improved. The scale and intensity of China′s R&D investment has been increasing, and the number of corporate patent applications has been among the top in the world. However, as a whole, there is still a big innovation gap with developed countries, and there is still a long way to go in the innovation capacity of the manufacturing industry. How to effectively promote the innovation capacity of the manufacturing industry has long been an important topic to policy makers, academic researchers, business managers and the public.S&T service is knowledge-intensive, technology-intensive and human-capital-intensive, and its professional services and technical services have effectively improved the added value of manufacturing industry and the technical content of products. With the development of economy, S&T service is showing the characteristics of agglomeration. Then, can S&T service agglomeration improve the technological innovation of manufacturing enterprises? What influence does it have on the technological innovation behavior of manufacturing enterprises? We can accelerate the development of S&T service, foster new drivers of innovative development in the manufacturing industry, fulfill innovation-driven transformation of China′s economy, promote deep integration of advanced manufacturing and modern service industry and build a modern economic system, which has very important academic value and practical significance, if the influence of S&T service agglomeration on manufacturing industry is well researched.To solve this problem, this paper uses the World Bank in 2012 China enterprise survey database and city level data to empirically analyze the effect of S&T service agglomeration on technology innovation of manufacturing industry, connecting macro S&T service agglomeration and technology innovation of micro manufacturing enterprises, making up for the deficiency research on the innovation impact of S&T service agglomeration at the micro field, providing a new idea for manufacturing enterprises to improve technological innovation ability and providing more direct evidence that S&T service agglomeration can promote the technological innovation of manufacturing industry. The research results of this paper are as follows:Firstly, S&T service agglomeration has a significant promoting effect on the innovation probability and innovation intensity of manufacturing enterprises, that is, S&T service agglomeration improves the extensive margin and intensive margin of technological innovation activities in manufacturing enterprises. On average, the probability and intensity of technological innovation output of manufacturing enterprises will increase by 22% and 4.7% for each unit increase of location entropy of S&T service. S&T service agglomeration improves the possibility and intensity of enterprise′s technological innovation activities, improves the participation rate of enterprise′s R&D and innovation activities, increases the investment intensity of technological innovation, and promotes the improvement of enterprise′s innovation ability and core competitiveness.Secondly, through the analysis of the impact on the technological innovation behavior, the results show that S&T service has only some positive effects on exploitative innovation and imitation innovation, the exploratory innovation, independent innovation and cooperative innovation was not significant at the present stage, which suggests that China′s current S&T service fails to satisfy well the qualitive improvement for technology innovation of manufacturing industry, and innovation-leading function of S&T service still needs to be further explored and improved. The conclusion of this paper enriches the research on the impact of the S&T service agglomeration on the technological innovation behavior of enterprises.Based on the above research conclusions, this paper puts forward specific policy recommendations from three perspectives: amplify agglomeration scale of S&T service, improve agglomeration quality of S&T service and strengthen industrial association between S&T service and manufacturing industry. From the perspective of related industry layout, this paper provides micro evidence on how S&T service agglomeration promotes technological innovation in manufacturing enterprises, and has important enlightenment significance on how to give play to the innovation promotion role of S&T service agglomeration to help the manufacturing industry for gaining competitive advantages.
