Abstract

Exploring the dynamic relationship and coupling coordination between urban industrial co-agglomeration and intensive land use is vital to ensure high-quality urban development. Based on an industrial co-agglomeration model, a revised intensive land use model, and a coupling coordination model, this paper comprehensively measured the urban industrial co-agglomeration and intensive land use coupling coordination in eight cities in the Chengdu metropolitan area from 2004 to 2018. It was found that despite the structural adjustment of the secondary and tertiary industries during the study period, the industrial co-agglomeration in the Chengdu metropolitan area fluctuated, the intensive urban land use had spatial characteristics that were decreasing from the center to the periphery, and while the general coupling coordination level was increasing, the increase rate in each city was different. The coupling coordination between the urban industry co-agglomeration and the intensive land use was found to have “low-high-low” spatial characteristics from the southwest to the northeast of the Chengdu metropolitan area, which revealed the core position of Chengdu. Suggestions are provided to improve the industrial co-agglomeration and intensive urban land use coupling coordination.

Highlights

Over the past 30 years, China has rapidly urbanized, with the urbanization rate reaching 59.58% in 2018 [1]
The urban industrial co-agglomeration level had risen, which indicated that the differences between the secondary and tertiary industry agglomeration levels in these cities had decreased
Based on Formulas (1) and (2), the industrial urban co-agglomeration levels in each Chengdu metropolitan area city were calculated, the results of which are shown in F6igofu1r2e 3

Summary

Introduction

Over the past 30 years, China has rapidly urbanized, with the urbanization rate reaching 59.58% in 2018 [1]. As a result of increased urban interactions and connectivity, metropolitan areas have been increasing [2] and there have been significant industrial agglomeration and intensive urban land use changes. When analyzing the urban development problems in China, it is necessary to examine the urban space scale expansions and urban population agglomerations, and to comprehensively consider upgrading urban industries and transforming economic growth patterns. As cities encompass both residential requirements and industry, it is necessary to carefully plan the use of urban land. There has been an increased focus on coordinated land use development and functional optimization in Chengdu’s current and future development planning [6]
