“圈层”结构、时空差异与能源强度——以十大城市群为例

【摘要】：借助于经济地理学的理论视角,使用城市引力模型对十大城市群"圈层"结构进行测度,然后对城市群"圈层"结构降低能源强度的影响程度及其时空差异进行分析。结果显示,成熟的城市群和适度的"圈层"结构更容易降低能源强度。从空间维度上看,东部城市群"圈层"结构显著降低了能源强度,但在0.45边界标准之后,降低能源强度程度明显变小。中西部城市群"圈层"结构降低能源强度程度小于东部城市群,大部分结果仅在10%水平上显著。从时间维度上看,相机抉择使得政府节能减排战略未能实现预期目标,短期内弱化了"圈层"结构降低能源强度效果。控制行政分割等变量发现,政府干预更容易凸显拥挤效应的约束作用,借助市场和空间的力量更有利于节能减排目标的实现。
[Abstract]:Based on the theory of economic geography, the paper measures the "circle" structure of the ten urban agglomerations by using the urban gravitation model, and then analyzes the influence degree and space-time difference of the "circle" structure of the urban agglomeration to reduce the energy intensity. The results show that mature urban agglomeration and moderate "circle" structure are easier to reduce energy intensity. From the spatial dimension, the "circle" structure of the eastern urban agglomeration reduces the energy intensity significantly, but after 0.45 boundary standard, the energy intensity decreases obviously. The "circle" structure of the urban agglomeration in the central and western regions reduces the energy intensity less than that of the eastern urban agglomeration, and most of the results are significant at the level of 10%. From the perspective of time dimension, the government's strategy of energy saving and emission reduction fails to achieve the expected goal, and weakens the "circle" structure to reduce the effect of energy intensity in the short term. By controlling administrative segmentation and other variables, it is found that government intervention is more likely to highlight the constraint effect of crowding effect, and the help of market and space forces is more conducive to the realization of energy saving and emission reduction targets.
