| 摘要: |
| 环渤海地区是我国最具综合优势和发展潜力的经济增长极之一。为促进环渤海地区的生态文明建设和经济可持续发展，文章采用三阶段DEA模型、Malmquist指数和空间自相关分析法，基于2006—2015年环渤海地区17个沿海城市的面板数据，动静态结合分析其生态效率和空间关联特征。研究结果表明：通过引入环境变量和运用相似SFA模型，剔除外部环境和随机误差的影响，可更加准确地测算区域生态效率；各城市的生态效率均有所提高，主要原因是技术进步；区域生态效率同时存在空间的相关性和差异性，空间格局处于动态变化中。 |

| Abstract: |
| The Bohai Sea rim region is one of the most economic growing poles of China's comprehensive advantages and developing potential.In order to promote the ecological civilization construction and sustainable economic development in the Bohai Sea region,the three stage DEA model,Malmquist index and spatial autocorrelation analysis method were used to analyze the ecological efficiency and spatial correlation characteristics of the 17 coastal cities in the Bohai Sea region,based on the panel data of 17 coastal cities in the ring region of 2006—2015.The results showed that by introducing the environmental variables and using the similar SFA model,eliminating the influence of the external environment and random error,the ecological efficiency of the region could be calculated more accurately;the ecological efficiency of each city was improved,the main reason was the technological progress,and the spatial correlation and difference existed in the regional ecological efficiency in the same time.The spatial pattern was in the dynamic change. |
