The Impact of Industrial Cooperative Agglomeration on High-quality Economic Development

At present, technological innovation has become the first driving force for the high-quality development of the regional economy. The high-tech industry has the characteristics of high intelligence and high technology intensiveness. It plays a vital role in the process of promoting economic growth. It is the focus of competition among countries today. However, our country's high-tech industry has been at the low-end link in the division of labor in the global value chain for a long time, which has restricted its scientific and technological innovation capabilities. It is urgent to adjust the regional industrial structure and seek new impetus for economic development. Producer service industry, as a heterogeneous industry with a high degree of relevance to high-tech industries, can improve the degree of industrial specialization and sub-engineering, and promote the high-endization of high-tech manufacturing. The synergistic agglomeration of high-tech industries and producer service industries can significantly enhance the innovation capabilities of high-tech industries and effectively promote high-quality economic development. Therefore, it is a realistic and urgent problem to clarify the mechanism of the impact of industrial collaborative agglomeration on high-quality economic development.Existing literature has conducted in-depth discussions on innovation and high-quality economic development, industrial collaborative agglomeration and innovation, and promoted the development of related theories. However, there are still the following shortcomings. First, some scholars have discussed the relationship between industrial collaborative agglomeration and economic development, but seldom paid attention to the relationship between industrial collaborative agglomeration and high-quality economic development. Secondly, there are few documents that incorporate industrial collaborative agglomeration, innovation capabilities and high-quality economic development into a unified framework for analysis. What is the mechanism of industrial collaborative agglomeration to promote high-quality economic development? Existing documents rarely involve it. Finally, there are both linear and non-linear relationships between industrial collaborative agglomeration, innovation, and high-quality economic development. Existing studies are often limited to the analysis of linear relationships between two variables, and there is a lack of non-linear relationships. This paper incorporates industrial synergistic agglomeration, innovation capabilities, and high-quality economic development into a unified framework, deeply analyzes the mechanism of industrial synergistic agglomeration to promote high-quality economic development, and builds a threshold model to collect 30 provinces and municipalities in mainland China from 2005 to 2019 (Tibetan factors). (Incomplete data, not included in statistics) High-tech industry and producer service industry collaborative agglomeration, high-quality economic development related data, accurate measurement of industrial collaborative agglomeration and its impact on high-quality economic development through innovation capabilities, and the use of ArcGIS software for industrial synergy visual analysis of the agglomeration level, in-depth analysis of the impact of industrial collaborative agglomeration on the high-quality development of the regional economy.Industrial collaborative agglomeration realizes the spatial diffusion of technology through technological externalities, promotes the technological progress of related enterprises in the region, improves the technological capabilities of enterprises, and drives high-quality economic development. Industrial collaborative gatherings have the following effects. Firstly, the specialized division of labor forms a specialized market for various supporting services, such as the talent, capital, and raw material markets. The specialized division of labor enables agglomeration enterprises to share various auxiliary services and form economies of scale. Secondly, sharing public facilities, reducing additional investment and geographical proximity can save freight and improve output efficiency. Finally, collaborative clustering enables technical and management personnel to gather through formal or informal exchanges to promote the dissemination and exchange of technical and management information among enterprises, which in turn increases technology spillover.The main conclusions of this paper are as follows. (1) Industrial collaborative agglomeration presents imbalanced characteristics. In terms of space, except for the western collaborative agglomeration areas (Sichuan, Chongqing, Guizhou, Shaanxi), industrial collaborative agglomeration presents high in the east and low in the west, and high in the coastal areas. The characteristics of low land, the Matthew effect is significant; in terms of time, the cooperative agglomeration of industries presents a four-legged evolutionary trend (Yangtze River Delta, Beijing-Tianjin-Hebei, Pearl River Delta and Western Cooperative Agglomeration Area). (2) The synergy between the industrial collaborative agglomeration and high-quality economic development of various provinces and cities is divided into four types: collaborative agglomeration and economic high-quality maintenance, collaborative agglomeration and enhanced economic high-quality, enhanced collaborative agglomeration, and enhanced economic high-quality. Corresponding to the high level of industrial synergistic agglomeration-high economic and high-quality development level, low industrial synergistic agglomeration level-low economic high-quality development level, low industrial synergistic agglomeration level-high economic and high-quality development level, high industrial synergistic agglomeration level-low economy and high Quality development level. (3) Industrial collaborative agglomeration has dual-threshold effects on innovation ability, innovation ability on high-quality economic development, and industrial collaborative agglomeration on high-quality economic development, and the impact effect is diminishing on the margin. Industrial synergistic agglomeration can significantly enhance regional innovation capabilities, but as the degree of industrial synergistic agglomeration further increases, its promotion of innovation capabilities shows a marginal diminishing effect. Regional scientific and technological innovation can drive high-quality economic development, but because the threshold for the transformation of scientific and technological innovation capabilities is getting higher and higher, it is becoming more and more difficult to transform scientific and technological achievements into productivity, resulting in a marginal diminishing effect. Innovative ability has different effects on high-quality economic development when the industrial collaborative agglomeration is in different threshold ranges, and the impact of innovative ability on high-quality economic development is diminishing positively.Based on the above conclusions, in order to promote the high-quality development of the regional economy, this article puts forward the following policy recommendations: (1) Promote the coordinated and balanced development of regional industries and eliminate the Matthew effect. First, each region should focus on improving the level of synergy and agglomeration of high-tech industries and producer service industries. Secondly, narrow the gap in the level of synergy and agglomeration of various regional industries, give full play to the knowledge spillover effect between high-tech industries and producer service industries in different regions, and realize the spatial spillover of technology. Finally, strengthen inter-regional industrial cooperation and promote the complementary development of industrial agglomeration. (2) According to the actual situation of industrial collaborative agglomeration and high-quality economic development in different regions, formulate targeted and differentiated policies to effectively improve the level of industrial collaborative agglomeration and high-quality economic development in various regions. (3) Improve the level of industrial collaborative agglomeration and innovation capabilities, Effectively promote high-quality economic development. On the one hand, pay attention to the improvement of the level of synergy and innovation of high-tech industries and producer service industries, and create a good industrial synergy atmosphere. On the other hand, promote the transformation of regional technological innovation capabilities and drive high-quality economic development. Encourage industry-university-research cooperation, accelerate the transfer and transformation of scientific and technological achievements, and stimulate the enthusiasm of innovation entities; Strengthen the management of the transformation process of scientific and technological achievements, support the development of regional and industrial technology markets, and improve the service functions of technology transfer institutions; Strengthen the guiding role of the government in the transformation of scientific and technological achievements, build a characteristic industrialization base, build a platform for achievement transformation, promote industrial upgrading; through multi-channel capital investment, guide the transformation of scientific and technological achievements, and promote high-quality economic development.
