【摘要】：利用传统统计方法和ESDA方法,在ArcGIS和GeoDa等软件的支持下,以人均GDP为测度指标,从时间、空间及影响因子三个方面对2001年~2011年长江流域区域经济差异进行分析。结果表明:(1)长江流域区域经济绝对差异在波动中持续扩大,而相对差异呈现出迅速缩小的趋势;(2)长江流域市域经济发展水平得到显著提高,空间分布呈现出明显的聚集特征;热点区范围在流域内出现自东向西不断扩散的态势,而以成都城市圈为内环的环状冷点区范围持续收缩;(3)长江流域区间差异对流域总体差异贡献最大,虽呈现出缩小的趋势,但仍然是区域经济的主要差异;(4)多元回归模型显示历史经济基础、区域发展策略及地理区位是导致长江流域区域经济差异扩大的主要原因,其中区域发展策略对区域差异的影响程度最深。
[Abstract]:Using the traditional statistical method and ESDA method, with the support of software such as ArcGIS and GeoDa, taking the per capita GDP as the measure index, from time. This paper analyzes the regional economic differences in the Yangtze River basin from 2001 to 2011 from three aspects of space and influencing factors. The results show that the absolute regional economic differences in the Yangtze River basin continue to expand during the fluctuation. The relative difference shows a trend of rapid reduction. (2) the level of urban economic development in the Yangtze River Basin has been improved significantly, and the spatial distribution shows obvious characteristics of agglomeration; The hot spot area is spreading from east to west in the watershed, while the ring cold point area with Chengdu city circle as the inner ring continues to shrink. 3) the regional differences of the Yangtze River basin contribute the most to the overall differences of the river basin, although they show a decreasing trend, they are still the main differences in the regional economy. 4) the multiple regression model shows the historical economic basis, the regional development strategy and the geographical location are the main reasons that cause the regional economic difference in the Yangtze River basin to expand. Among them, regional development strategy has the most influence on regional differences.

【正文快照】： 区域经济发展差异作为一种非均衡发展的地理现象[1],其发展演变对区域社会发展产生重要影响,是经济研究领域的一个传统论题。改革开放以来,学术界对区域经济差异研究呈现出两个显著趋势:一是研究尺度的多元化,研究范围从国家、省、市[2-7]层面向县域[8,9]及更小区域为研究单元
