环渤海地区城市绿色经济发展的时空分异特征——基于脱钩与脱钩追赶的衡量

Spatial-temporal Differentiation Characteristics of Urban Green Economy Development in the Bohai Rim—Based on the Measurement of Decoupling and Chasing Decoupling

环渤海地区作为我国重工业发达的区域之一,环绕首都地理位置的特殊性及较为突出的生态环境问题,更应加大力度建设生态、发展绿色经济。基于脱钩模型、脱钩追赶模型对环渤海地区各城市经济发展和环境污染关系进行分析,探讨环渤海地区绿色经济发展水平。研究发现,环渤海地区经济发展和环境污染的脱钩效果波动变化,绿色经济发展总体趋势向好;各城市绿色经济发展差异巨大,沿海城市较好于内陆城市,经济发展程度较高的城市绿色经济发展也较好;各城市在与标杆城市绿色追赶的过程中,绿色经济发展差距仍然很大。通过对环渤海地区城市绿色经济发展的探讨,希望对环渤海地区经济转型,促进绿色经济发展提供一定意义的参考。

The Bohai Rim,as one of the developed regions of heavy industry in China,should protect ecology and develop green economy due to its special geographical location around the capital and prominent ecological and environmental problems.Based on the decoupling model and chasing decoupling model,the paper analyzed the relationship between economic growth and environmental pollution,and examined green economy level in the Bohai Rim.The results show that the decoupling effect of economic development and environmental pollution in the Bohai Rim is fluctuating,and the overall trend of green economy is better;that green economy development varies among cities,and is better in the coastal cities than in the inland cities,and the developed cities also have better green economic growth;that there is a big gap in the development of green economy in the process of catching up with the benchmark cities.Through the analysis of green economy development in the Bohai Rim,the paper is expected to provide some reference for the economic transformation and green economic development in the Bohai Rim.
