Abstract:

The Guanzhong Plain City Cluster is located in northwest China, in the provinces of Shaanxi, Shanxi, and Gansu, a less developed region of China. The Guanzhong Plain City Cluster, the second-largest in inland China and one of the country’s eight most important city clusters serve as a vital gateway to western China. The development of the Guanzhong Plain City Cluster plays an important exemplary role and is strategically significant for regional harmonious development, new urbanization construction, and the Belt and Road Initiative. The research used UCINET and ArcGIS to analyze the evolution of 11 cities’ economic network structure in the Guanzhong Plain City Cluster from centrality, influences, “core-peripheral” structure, and cohesive subgroups by social network analysis using city economic data from 2008 to 2018. Then the regression model is constructed to analyze the influence of network structure properties on economic growth, and the suggestions to improve regional economic growth has been put forward from the perspective of economic network structure. The findings indicate that (1) the centrality of the city cluster’s network is insufficient with a decreasing trend, city centrality degree varies greatly, and the changes in centrality are different in different cities; regional sub-centers are severely underdeveloped, and the development of the economic network is dominated by polarization effect, indicating that regional development is unbalanced. (2) Xi’an has the greatest efficiency and lowest constraint, as well as the greatest influence with a growing trend in the city cluster, while the influence of non-core cities is relatively declining, which causes the “shadow effect” on surrounding cities. (3) The internal agglomeration of cohesive categories evolves from loose to close; in 2018, the cohesive subgroup presents a significant hierarchy, displaying a “pyramid” distribution; city subgroups and administrative division evolve from uncoupled to fully coupled, indicating that geographical proximity and administrative division are endogenous driving forces for the development of an economic network of the Guanzhong Plain City Cluster. (4) Based on the “core-peripheral” structure analysis, the city cluster has a low level of mean coreness with the growing trend which means that the degree of agglomeration in the economic network is gradually increasing; The economic network developed a core-peripheral structure, first with Xi’an as the core in 2008, and then with Xi’an and Xianyang as the core group between 2013 and 2018. (5) Regression analysis results show that the centrality, influence, and agglomeration of urban nodes have different effects on urban economic growth; more specifically, centrality and efficiency have a significant and positive correlation with economic growth, the constraint has a positive correlation with economic growth and coreness is non-significant.
