Abstract:

Considering the new-type urbanization background, the nearby urbanization model provides a practical approach toward eliminating the disadvantage of trans-regional urbanization and promoting urbanization. This study establishes the indexes of the nearby urbanization rate (NU), contribution to nearby urbanization (CNU) and trend of contribution to nearby urbanization (TNU), to analyze the spatial differentiation features of nearby urbanization in central and western China from 2000 to 2015. Moreover, this study explores the determinant factors and influencing mechanism of the spatial differentiation of nearby urbanization in the study region. Results show that: (1) From 2000 to 2015, the population of nearby urbanization increased from 196 million to 347 million and the NU increased from 28.16% to 46.89%. (2) Based on the analysis of the CNU, we found that the main source of nearby urbanization was the population registered in the local town, but the contribution of local town to nearby urbanization (CNUt) gradually declined over the study period. The areas with high CNUt were widely distributed in central and western China in 2000, but by 2015, they were restricted to Sichuan province. Meanwhile, the contribution of local county to nearby urbanization (CNUc) increased and the contribution of local province to nearby urbanization (CNUp) varied slightly. Most areas with high CNUp were provincial capital cities, resource-based cities or pastural cities. (3) Based on the analysis of the TNU, the trend of the contribution of local county to nearby urbanization (TNUc) exceeded the trend of the contribution of local province to nearby urbanization (TNUp), while the trend of the contribution of local town to nearby urbanization (TNUt) exhibited the least influence. Therefore, examining nearby urbanization based on the county-level spatial unit was advantageous in most regions; however, in the northwestern border regions and provincial capital cities, the provincial level was more applicable. (4) The spatial differentiation of nearby urbanization was determined based on the integrated results of various influencing factors, including natural environment, economic development, non-agricultural industries, urban public services, transportation accessibility, and the influence of local administration.
