重庆三峡库区高质量发展水平的测度及空间差异影响因素分析

Measurement of High-Quality Development Level and Analysis of Influencing Factors of Its Spatial Differences in Chongqing Three Gorges Reservoir Area

【目的】考察重庆三峡库区(以下简称库区)高质量发展现状及有关影响因素。【方法】在阐述高质量发展内涵的基础上,从经济绩效、经济结构、开放创新、绿色环保、社会共享等5个方面构建了库区高质量发展水平的评价指标体系,基于2018年库区有关数据,运用熵权TOPSIS、地理探测器等方法对库区高质量发展水平进行测度并对有关库区高质量发展水平空间差异的影响因素进行分析。【结果】1)2018年库区高质量发展水平较低,各区县高质量发展指数平均值仅0.2692,且存在着明显的空间差异,呈"库尾高,库腹低"的空间分布格局,并表现为由库腹向库尾逐渐递增的趋势。2)高质量发展各分项指数差异明显,经济绩效指数、经济结构指数、开放创新指数和社会共享指数较低,绿色环保指数较高,库区高质量发展的潜力较大。3)对库区高质量发展水平空间差异起主导作用的因素主要为人均固定资产投入占比、森林覆盖率、适龄劳动力数量、人口城镇化率、坡度、第三产业产值占比等,各影响因素交互作用后表现为双因子和非线性增强。【结论】研究成果初步展示出库区高质量发展的现状及空间分布格局,分析了有关库区高质量发展水平空间差异的影响因素并确定了它们的影响力,为库区全面实现高质量发展提供了理论依据和参考资料。

[Purposes]To investigate the current status of high-quality development in the Chongqing Three Gorges Reservoir Area(referred to as the Reservoir Area hereinafter)and related influencing factors.[Methods]On the basis of elaborating the connotation of high-quality development,an evaluation index system for the high-quality development level of the reservoir area was constructed from the five aspects of economic performance,economic structure,open innovation,green environmental protection,and social sharing,based on the 2018 reservoir area relevant data,using entropy weight TOPSIS,geographic detectors and other methods to measure the high-quality development level of the reservoir area and analyze the factors affecting the spatial differences in the high-quality development level of the reservoir area.[Findings]1)In 2018,the level of high-quality development in the reservoir area was low.The average value of the high-quality development index of each district and county was only 0.2692,and there were obvious spatial differences.And it shows a gradual increasing trend from the belly of the library to the tail of the library.2)The development indexes of each sub-item have obvious differences.Among them,the economic performance index,economic structure index,open innovation index,and social sharing index have low development levels and great development potential;the green environmental protection index has a high level.3)The factors that play a leading role in the spatial differentiation of the high-quality development level of the reservoir area are mainly the proportion of per capita investment in fixed assets,forest coverage,the number of labors of the right age,the urbanization rate of the population,the slope,the proportion of the output value of the tertiary industry and other factors.After the interaction of the influencing factors,the two factors and nonlinear enhancement are shown.[Conclusions]In conclusion,the research results have initially demonstrated the current status and spatial distribution pattern of high-quality development in the reservoir area,analyzed the influencing factors of the spatial differences in the high-quality development level of the reservoir area,and determined their influence,which provides a comprehensive view of the reservoir area.The realization of high-quality development provides theoretical basis and reference materials.
