时空关联视角下湖南省经济发展水平的路径研究

Study on the Economic Development of Hunan Province from the Perspective of Space-Time Correlation

时空路径的研究方法能够有效地解决经济地理学研究过程中时间和空间相互分离的问题.采用时空路径的研究方法,选取1978年至2015年间9个年份的湖南省人均GDP以及各地市人均GDP作为基础数据对湖南省经济发展水平的路径进行研究.结果表明:长株潭地区经济发展水平始终高于全省平均水平,而以邵阳、娄底、怀化等为代表的地市经济总量虽然保持增长但其发展水平与全省平均水平的差距逐渐增大.部分发达地市与欠发达地市的经济时空路径在改革开放以来的发展历程中鲜有交集,经济发展过程中地区差异问题日趋突显.各地市经济在发展水平和时空路径分布上的差异显示出湖南省部分地市经济出现"组团式落后"的局面.

The research method of space-time path can effectively solve the problem of the separation of time and space in economic geography study.The research adopts the space-time path method and selects 9 years'per capita GDP of Hunan province and prefecture-level cities between 1978 and 2015 as the basic data,aiming to study the path of the economic development level in Hunan province.The results are as follows:the economic development level in Changsha-Zhuzhou-Xiangtan area has always been higher than provincial per capita.In contrast,in some prefecture-level cities like Shaoyang and Loudi,the gap between their GDP,which remains growing though,and the provincial average is becoming increasingly wider.The economic space-time paths of the developed cities and underdeveloped cities rarely intersect in the course of economic development since the reform and opening up,which shows that the issue of regional differences in the process of economic development has become increasingly prominent.Thus,according to the differences of the development level and the space-time path distribution of local cities,part of the cities in Hunan province show the situation of"group backwardness".
