摘要： 基础设施建设是贫困地区经济增长步入正轨的先行条件，也是政府支持贫困地区经济发展的必然举措。基于三峡库区面板数据的数据包络分析和动态空间滞后模型研究，对基础设施效率以及时空溢出效应进行探讨。结果显示：基础设施效率整体上明显改善，但特困区县基础设施效率处于低水平陷阱之中；基础设施效率存在显著为正的时空溢出效应，效率提升具有显著的动态促进和空间协同；优势地区基础设施效率的时间溢出效应更加突出，劣势地区基础设施效率的空间溢出效应较为明显。基于上述结论，如何破解协调失灵和改善空间配置是三峡库区基础设施效率进一步提升的关键所在。

Abstract: Infrastructure construction is the first condition for economic growth, and also the necessary measures for the government to support economic development of the poor regions. Through the research of data envelopment analysis and dynamic spatial lag model in Three Gorges region, this paper discusses the infrastructure investment efficiency and its spatial and time spillover effect. The results demonstrated that the infrastructure investment efficiency overall has improved significantly, but some poor regions' infrastructure investment efficiency may be at a low level equilibrium trap. Infrastructure investment efficiency has significant positive spatial and time spillover effect, which has significant dynamic promotion and spatial coordination. The time spillover effect of infrastructure investment efficiency is more prominent in advantageous region, and the spatial spillover effect of infrastructure investment efficiency is obvious in disadvantageous region. Based on the above conclusions, the key to the further improvement of infrastructure investment efficiency in the Three Gorges region is to break the coordination failure and improve the space allocation.

Key words: Three Gorges region, infrastructure efficiency, spillover effect, dynamic spatial lag model
