中文摘要：

基于多中心网络城市理论和集群网络结构竞争理论,在构建城市群网络空间绩效分析框架和评价指标体系的基础上,采用DEA的BCC模型和Malmquist指数模型,对2008～2010年环鄱阳湖区城市群42个城市空间网络联系效率进行了分析。研究表明：（1）从效率总体比较来看,环鄱阳湖区内的大部分城市处在空间网络联系的生产前沿面上,不在生产前沿面上的城市逐渐向生产前沿面靠近;（2）从效率分解来看,环鄱阳湖城市群空间网络绩效的变化是技术效率和技术水平共同作用的结果,其中,技术水平起的作用更为明显;（3）从效率空间差异分布看,环鄱阳湖区城市群空间网络绩效呈现核心区大于边缘区、边缘区大于外围区的规律,而城市群空间网络发展速度呈现外围区最高,核心区次之,边缘区最低的规律。

英文摘要：

Based on the multi-center network urban theory and cluster network structure competition theo- ry, depended on the building of urban spatial network structure performance analysis framework and evaluation index,we used DEA-BCC model and DEA-Malmquist index model to analyze the space network contact efficiency of 42 cities around the Poyang Lake during the year 2008 to the year 2010. The following conclusions are put forward in this paper. （1）Most cities around the Poyang Lake were in the spatial network contact of production frontier surface, and cities which were not in production frontier area are gradu- ally moving to the production frontier surface by the comparison of efficiency. （2）From the efficiency decomposition,the change of the space network structure performance of cities around the Poyang Lake was affected by the technical efficiency and technical level transformation, and technical level had a visible effect on it. （3）On the distribution of efficiency of spatial difference, the spatial network structure perform- ance of cities around the Poyang Lake presented the regular that performance of center zone is higher than that of the marginal zone,and performance of the marginal zone is better than that of the peripheral zone. However,the speed of urban space network development showed a regular that marginal zone has the fastest speed,followed by the center,and the peripheral zone has the slowest speed.
