摘要/Abstract

摘要：

通过四川省改革开放以来的产业结构演化及其城市化响应过程分析,揭示不同产业发展的城市化响应特征,为四川省产业结构调整提供科学依据。提出“第二产业发展的城市化响应系数R₍₂₎”和“第三产业发展的城市化响应系数R₍₃₎”2个概念,分析了四川省改革开放以来二者的变化特征,探讨了不同产业与城市化过程的内在联系。根据不同产业发展的城市化响应水平的关联情况,将四川省21个市州划分为3类：一致响应型、偏R₍₂₎响应型、偏R₍₃₎响应型。运用多元线性回归模型,以逐步回归法确定产业结构演变与城市化响应的主要关联因素,探究其作用机制。研究表明：城市经济密度、空间集聚能力、人口集聚能力和城镇体系水平是影响四川省产业结构演变的主要因素,据此对不同类型区域提出相应的调控对策：对一致响应型区域统筹城乡经济,提高产业发展水平;偏R₍₂₎响应型区域经济发展水平较低,应控制城市规模,加快第二产业发展;对偏R₍₃₎响应型区域应调整城镇体系,加快第三产业发展。

Abstract:

The relationship of regional industrial structure and urbanization is an important part of Urban Geography. By analyzing the evolvement of industrial structure and its urbanization response in Sichuan Province since the reform of China in 1978, the article revealed the characteristics of the urbanization response of the industrial structure evolvement at different industries, and tried to perfect the theory of urban development and to provide a scientific basis for the industrial restructuring of Sichuan Province. This article proposed two concepts, which are Coefficient of Urbanization Response to the Secondary Industry, represented with the symbol R₍₂₎, and Coefficient of Urbanization Response to the Tertiary Industry, represented with the symbol R₍₃₎. Taking Sichuan Province as an example, the author described their characteristics since The Reform of China in 1978, and analyzed the internal relations of the development of industries and the urbanization. The results show that the urbanization response to the industries in Sichuan Province presents spatio-temporal differences. Both the coefficient of urbanization response to the secondary industry and the coefficient of urbanization response to the tertiary industry increased, and its coefficient of urbanization response to industrial structure increased. The coefficient of urbanization response to the secondary industry decreased and the coefficient of urbanization response to the tertiary industry increased, while the change of coefficient of urbanization response to industrial structure depends on the change amplitude of the former two coefficients. According to the combinations of respective urbanization response strength in different industries, 21 cities and prefectures in Sichuan Province were divided into three categories: consistent response, partial secondary industry response, and partial tertiary industry response. The correlation mechanism between the evolvement of industrial structure and urbanization was analyzed through multiple linear regression, and the main factors were determined by stepwise. It was showed that the major factors to the evolvement of the industrial structure are urban economic density, spatial concentration, population concentration and urban system, which play a role in the different aspects of the evolvement. Because of different strength of urbanization response of regional industrial structure evolvement, different regulation measures should be taken. In the consistent response, urban economy and rural economy should be coordinated to upgrade industrial structure. In the partial secondary industry response which economic development are junior,the development of the secondary industry should be sped up preferentially, and the size of the cities should be controlled. In the partial tertiary industry response, the urban system should be properly adjusted, and the development of the tertiary industry should be accelerated. The regulation should also take the main functional area planning and the trends of urbanization response into account.
