东北地区绿色发展水平时空动态演变与障碍因素

以"人地协调"发展理念和"过程+格局+机制"思维范式为切入点,构建了基于DPSIR模型的绿色发展水平指标体系,运用熵权TOPSIS模型、障碍度模型和GIS空间可视化等方法对2008-2017年东北地区各城市的绿色发展水平时空分异特征与障碍因素进行实证研究。结果表明：①研究期内东北地区各城市绿色发展水平总体呈现从"小差距低水平"逐渐向"大差距高水平"转变的时序特征,空间分布大致呈现自北向南阶梯式递减的格局特征,且空间集聚效应显著。②东北地区各城市经济发展水平与绿色发展水平之间并非完全呈正相关关系,即,经济发展水平越高的城市,绿色发展水平不一定越高;而经济发展水平较低的城市,绿色发展反而达到较高的水平。这可能与区域资源环境承载力的大小有关。③东北地区各城市绿色发展水平时空分异的作用机制不尽相同,其中,资源禀赋条件、经济发展状况、政府投资规模在绿色发展水平的变化中起着重要的作用,同时也是导致东北地区绿色发展水平不同阶段呈现不同进化特征的主要原因。

Spatio-temporal pattern and obstacle factors of green development level in Northeast China

Based on the development concept of the coordinated man-earth relationship and thinking paradigm of process-pattern-mechanism, this paper constructed an index system of green development level using the Driving Force-Pressure-State-Impact-Response model. Then, we explored the spatio-temporal characteristics and obstacle factors of green development level in Northeast China from 2008 to 2017 using the entropy weight TOPSIS model, obstacle model and GIS spatial visualization. There were three main findings. First, during the research period, the green development level in Northeast China gradually shifted from small gap at an overall low level to large gap at an overall high level. The spatial distribution presented a pattern of gradually decreasing from north to south with significantly spatial agglomeration. Second, the relationship between the economic development level and green development level in Northeast China was not completely positive. In other words, a city with higher economic development level did not necessarily have higher green development level, while a city with a lower level of economic development might have a higher level of green development, and this might be related to the regional resources and environment carrying capacity. Finally, the mechanism of spatio-temporal differentiation of green development level in Northeast China was not identical, while resource endowment conditions, economic development status and government investment scale played vital roles in the change of regional green development level.
