摘要
为了揭示重庆市38个区县在2005—2019年间区域发展空间分异情况,本研究基于城镇要素集聚能力指数,结合崔王指数、障碍度评价法展开实证分析。结果表明:(1)区域发展水平整体呈螺旋式上升趋势,空间上呈现出明显的核心(主城区)—外围(非主城区)结构特征,但分异程度在不断下降。(2)非农产业产值、人均GDP、非农就业人数、年末金融机构贷款余额、公共财政预算收入、空间规模以上企业总产值等因子是导致重庆市38个区县城镇要素集聚能力空间分异的关键性因子,其作用机理与重庆市地形区位、要素流动可达性和贫困区县空间分布所形成的“发展势能”的空间分异密切相关。(3)为了实现要素自由流动和区域协调发展,提出进一步强化主城区的核心集聚能力和扩散带动作用、弱化地形对空间相互作用的影响、构建“一圈两翼、一主两副”空间结构、深化“走出去、引进来”对外开放战略、强化(科技、体制机制、人才等)创新和生态文明建设引领作用等的对策建议。研究表明源于城镇要素集聚能力的区域发展空间分异研究方法,可以形象地将要素移动呈现在“发展势能”和要素移动成本的变化曲线中,对于深挖区域发展空间分异的主要影响因素及其形成机理具有较强的解释力;重庆市可以从区域城镇要素低成本自由流动、核心对外围辐射带动作用层面构建区域协调发展实现路径。
In order to reveal the spatial differentiation of regional development among 38 districts and counties in Chongqing from 2005 to 2019,this article conducts an empirical analysis based on the urban factor agglomeration capacity index,combined with the Cui Wang index and obstacle degree evaluation method.Results show as follows.(1)The regional development level of Chongqing is gradually increasing periodically,but in a state of significant disequilibrium.There are obvious spatial differentiation characteristics and polarization between the core(main urban area)and the periphery(non-main urban area),which is more serious.However,it is declining over time.(2)Factors including non-agricultural industry output value,per capita GDP,non-agricultural employment,year-end financial institution loan balance,public budget revenue,and total output value of enterprises above the designated size are key obstacles that restrict the coordinated regional development of Chongqing.Their formation mechanisms are closely related to the topography and location,and the spatial distribution of poverty-stricken counties.(3)In order to realize the free flow of elements and the Chongqing regional coordinated development,this paper proposes to further strengthen the core agglomeration capacity and diffusion driving effect of the main urban area,weaken the influence of topography on the spatial interaction,build a“one circle,two wings,one main and two sidelines”spatial structure,and deepen the“going out,bringing in”to the outside world countermeasures and suggestions for opening up strategies,strengthening(science and technology,institutional mechanisms,talents,etc.)innovation and leading role in the construction of ecological civilization.Research results show that the research method of spatial differentiation of regional development derived from the agglomeration capacity of urban elements can vividly present the movement of elements in the curve of“development potential”and the cost of factor movement,which is the main influencing factor for the spatial differentiation of regional development.Its formation mechanism has a strong explanatory power.Chongqing can construct a path for the regional coordinated development from the level of the free flow of regional urban elements at low cost and the core role in the peripheral radiation.
