The traditional regional development idea, with geographical distance as the boundary, is gradually being broken. For example, there has been a change in the relationship between central cities and peripheral cities, from a driving role and one based on technological competition, to one of technological complementarity. However, few studies have investigated the central and peripheral cities of innovation clusters. There are also few studies that have explored the evolution of technological structure between the central and peripheral cities of innovation clusters, and the convergence of economic growth.This paper redefines the central and peripheral cities of innovation clusters, by focusing on technology complexity and the inter-city technology complementarity index. The study applies the innovation cluster center and peripheral city economic development difference index, β convergence model, and spatial panel econometric model to deeply analyze the convergence of economic growth of innovation cluster central and periphery cities under a complementary technology system. The study reveals the following findings. There has been a narrowing of the difference in economic development between the innovation cluster center and the surrounding cities. The level of technological complementarity has increased when comparing the central city and the peripheral cities of innovation clusters, accelerating absolute economic growth of the two cities. This is demonstrated by the absolute β convergence and conditional β convergence trend. The results have a significant spatial effect. Based on the evolution of the technological structure of the innovation cluster center and periphery cities, as time passes, the technological complementarity between the center and periphery cities increases. In contrast, technological competition first rises and then falls. That is, the technological structure of the center periphery cities reflects a transformation from technological competition to technological complementation. Under the competitive technology system, there is no absolute β convergence and conditional β convergence in the economic growth of the peripheral cities in the innovation cluster center. The technology competition between the center and the peripheral cities inhibits the economic growth convergence of the innovation cluster. Improvements in the level and trend of collaborative innovation in peripheral cities help improve the degree of technology complementarity between the innovation cluster center and peripheral cities. However, improvements in the level and trend of collaborative innovation in the central cities do not promote the increase of technology complementarity between the center and peripheral cities.Compared with previous studies, this paper first re-identifies the central and peripheral cities of innovation clusters, by using the technology complexity index and inter-city technology complementarity index. The study also repositions the central cities from the perspective of innovation drive, and re-conceives the relationship between the central cities and peripheral cities from the perspective of inter-city technology correlation and interaction. Next, based on the division of innovation clusters with respect to central and peripheral cities, this paper applies the innovation cluster center periphery economic development difference index, β convergence model, and spatial measurement model to discuss the impact of innovation cluster center and periphery technology complementarity on its economic growth convergence. In addition, this paper further analyzes the evolution of technology structure between central and peripheral cities, and the driving factors of technology complementation. This helps deepen our understanding of the internal relationship between the center and periphery technology complement of innovation clusters and the convergence of economic growth.This study provides empirical evidence and policy insights to continuously deepen the development pattern of innovation clusters, promoting the transformation of the innovation cluster center and periphery technology structure from technology competition to technology complementarity. This can also help build a regional economic layout with complementary advantages and high-quality development. | | 查看全文 相关附件： 下载数据代码附录 |
