Research on the Regulation of Industrial Structure in the Mid-Southern Liaoning Urban Agglomeration from the Perspective of Spatial Connection

Industrial structure adjustment is an important way to promote the integration of regional industrial development. This paper takes the spatial connection as the starting point, combines the improved gravity model with the spatial deviation share expansion model, quantitatively analyzes the status quo of the urban agglomeration industrial structure from 2000 to 2015, and proposes the direction of regulation and optimization. Conclusions: (1) From 2000 to 2015, the interaction force of urban space was significantly enhanced with significant spatial directivity, and the neighboring cities with high accessibility had strong spatial interaction forces. The spatial pattern of urban space has undergone a fundamental change, and there is a path dependence. It evolved from a “semicircle” divergence to a “concentric circle” divergence. (2) The urban agglomeration in mid-southern Liaoning had the effect of industrial structure, but had not yet formed the effect of spatial competitiveness and spatial location from 2000 to 2015. (3) The industrial structure adjustment of urban agglomerations is mainly based on the secondary and tertiary industries, focusing on improving the industrial structure effect, spatial competitiveness effect, and spatial location effect of the secondary industry.
