综合利用泰尔指数、空间重心模型以及成本评价模型,对2002—2013年松花江生态经济走廊流域经济时空分异与驱动机制进行研究,结果发现:1流域经济差异程度演变特征各异,且流域经济差异程度呈现中游>上游>下游的发展特征,中游地区经济发展对于整个流域经济差异情况发挥重要作用。2流域经济发展时空分异现象明显,上游经济发展水平最高,但增速趋缓,下游发展水平最低,但速度激增。另外中低水平及低水平发展区占据主体,但数量趋减,流域经济虽有提升,但整体水平依然较低。3环境成本呈现中游>上游>下游的特征逐渐演化为中游>下游>上游的特征。另外流域不同类型城市经济发展的外部成本情况各异,综合型城市外部成本最低,资源型城市以及区域型城市外部成本较高。4流域上中下游经济发展时空分异的驱动机制各异,上游地区的驱动机制为所有制结构、产业结构、环境管理与政府调控,而中游地区为所有制结构与外商投资,下游地区为所有制结构、政府调控与科学技术。
Utilization Theil index, the focus of the model space and cost evaluation model, 2002--2013 Economic Songhua River Basin Ecological - Economic Corridor time and space difference and driving mechanism study found that: the degree of economic disparity 1 River since different characteristics and basin The degree of economic difference presents the characteristics of development in the middle reaches> the upper reaches> the lower reaches. The economic development in the middle reaches plays an important role in the economic disparity in the entire basin. 2 The spatial and temporal differentiation of economic development in the basin is obvious, with the highest level of economic development in the upper reaches, but the growth slowed down and the development level of the lower reaches was the lowest, but the speed surged. In addition, low-level and low-level development zones occupy the main part, but the numbers tend to decrease. Although the economy of the valley has been upgraded, the overall level is still low. 3 Environmental costs show the characteristics of midstream> upstream> downstream gradually evolve into midstream> downstream> upstream. In addition, the external costs of economic development in different types of cities are different, the external cost of integrated cities is the lowest, and the external costs of resource-based cities and regional cities are higher. Time and space downstream economic development drive mechanism of differentiation 4 different river basin, the drive mechanism for the upper reaches of the ownership structure, industrial structure, environmental management and government regulation, and the middle reaches of foreign investment and ownership structure for the downstream areas ownership structure, Government Regulation and Science and Technology.
