省际边缘区区域经济差异的时空格局与形成机理——以鄂豫皖赣为例

Spatio-Temporal Pattern and Mechanism of Economic Development Discrepancy in Provincial Border-Regions: A Case Study of Hubei-Henan-Anhui-Jiangxi

以鄂豫皖赣省际边缘区为研究视角,运用AHP-熵值组合赋权、模糊聚类、ESDA以及GIS可视化等方法对边缘区区域经济差异的时空格局进行了分析。研究发现:①鄂豫皖赣省际边缘区总体经济发展水平和经济相对发展率均较低,区域差异逐渐缩小,经济发展陷入低水平的恶性循环;县(市)经济发展水平在空间上有低聚高散的特征,格局相对稳定;低水平县(市)以边界线为轴线向左右扩展,边界效应日益明显;县域经济发展水平具有空间集聚性,但整体空间集聚性较弱,低水平俱乐部趋同效应明显。②在自然区位、经济条件、政府导向、空间作用及边界阻隔的影响作用下,产生的"桥梁效应"远远小于"切变效应",形成了边缘区区域经济格局。

Based on Hubei-Henan-Anhui-Jiangxi as the research angle, the spatio-tem-poral pattern of provincial border- regions economic differences were analyzed. The study found that： （1）The economic development and marginal rates of counties in Hubei-Henan-Anhui-Jiangxi provincial border-regions are in a low level ,relative economic development rate is low, economic development evolved into a vicious circle of low level; the economic development of counties in space has the characteristic of ＂high-level scatters,low-level gathers＂, low level counties spread to all around along boundary line,and boundary effects become increasingly evident ; the county economy development level of spatial agglomeration, but overall space agglomeration is weak, club convergence effect of low level shows obviously. （2）Under the effect of natural location, economic base, economic structure, the government ,border barrier and macroeconomic environment, the resulting ＂bridge effect＂ is far less than ＂shear effect＂, forming the pattern of regional economy.
