Abstract
Strategic emerging industries (SEIs) are an important industrial policy to promote innovation, develop advanced manufacturing, and upgrade the economy in China. The research explores the impact of SEIs on urban economic growth in mainland China, from agglomeration externalities and network externalities. The results show that SEIs have a significant impact on growth, and network externalities are generally more important than agglomeration externalities. Although the agglomeration of large-scale listed enterprises in the city promotes growth, too many large enterprises in the cluster, that is, the lack of small and medium-sized supporting enterprises, will harm urban growth. Meanwhile, a city with a higher degree of centrality has a larger GDP, but the strength has a negative impact.
Highlights
Strategic emerging industries (SEIs) are those key industries that the Chinese government considers to have an important impact on global economic competition. ose, include 9 industries: new generation of information technology industry, high-end equipment manufacturing industry, new material industry, bioindustry, new energy automobile industry, new energy industry, energy conservation and environmental protection industry, digital creative industry, and related service industry
7 out of 9 industries belong to manufacturing, so the agglomeration economy, that promotes the rapid growth of manufacturing, has an impact on the outlay and development of SEIs
Compared with the cooperation network based on spatial proximity in industrial clusters, network externality emphasizes the benefits from the information or financial connections outside the region or city. erefore, network externality highlights the impact of nonlocalization
Summary
Strategic emerging industries (SEIs) are those key industries that the Chinese government considers to have an important impact on global economic competition. ose, include 9 industries: new generation of information technology industry, high-end equipment manufacturing industry, new material industry, bioindustry, new energy automobile industry, new energy industry, energy conservation and environmental protection industry, digital creative industry, and related service industry. Many advanced manufacturing industries are important; they are affected by both the agglomeration economy and network externalities. Complexity e benefits of local development from agglomeration economies mainly come from three aspects: close upstream and downstream industrial connections, knowledge and information spillover, and large-scale labor market pool [1,2,3]. Compared with the cooperation network based on spatial proximity in industrial clusters, network externality emphasizes the benefits from the information or financial connections outside the region or city. Meijers and Burger [18] recently argued that the concept can be generalized to network connectivity between large and small cities It means small and medium cities can gain benefits by being well-positioned in both geographic space and urban networks. One of the purposes of the research is to answer which externalities are more important for ESIs and urban growth
