摘　　要：紧凑城市理念被认为可以有效提高城市经济发展效率,减少城市在开发建设、资源配置等方面的低效率。为探究我国城市紧凑度和城市效率的时空演变及两者间的相关性,本研究以吉林省地级及以上城市为研究对象,研究时间段选择为2000—2013年。研究主要分为三个部分。第一部分,运用熵值法,对吉林省地级及以上城市的紧凑度时空演变特征进行研究,研究发现,吉林省城市紧凑度平均水平较低,并且空间分布极不均衡,受区位和经济发展水平影响较大,高紧凑度城市基本位于哈大城市走廊一线。第二部分运用DEA数据包络模型,对吉林省城市效率演变特征进行研究,结果显示,吉林省城市效率在经过了长期的反复波动后于2012年步入快速增长阶段,受多种因素影响,各城市全要素生产率增长节奏迥异,但都表现出与技术进步一致的变动性,城市经济发展对新技术、新的生产要素投入的依赖较大,资源利用效率整体较低。第三部分运用R语言对吉林省城市紧凑度与城市效率的相关性进行了研究,两者间存在极弱的相关性,接着借助象限图法得出两者在不同时间段内存在一定程度的同步性,紧凑度提升时大部分城市的城市效率会出现提升,紧凑度的下降不一定有效引起城市效率同步下降。The concept of compact city is considered to effectively improve the efficiency of urban economic development and reduce the low efficiency in construction and resource allocation. In order to explore the spatial and temporal evolution of urban compactness and urban efficiency in China and the correlation between them, this study took Jilin Province as the research object, the period between 2000 and 2013 as the study time period. First, it analyzed the compactness space evolution characteristics of Jilin Province by using entropy method. It is found that the average level of urban compactness in Jilin was low, and the spatial distribution was extremely uneven, which is greatly influenced by location and economic development level. High compactness city was located in the Harbin-Dalian City line corridor. Second, it analyzed evolution characteristics of urban efficiency in Jilin Province by using the Data Envelopment Model. The results showed that the urban efficiency of Jilin Province entered a stage of rapid growth in 2012 after a long period of repeated fluctuations. The rate of urban efficiency was different, which was caused by various factors, but both consistent with changes in technological progress. The economic development of the city was dependent on the new technology and the new production factors, and the efficiency of resource utilization was relatively low. Third, it analyzed the correlation between the compactness and efficiency in Jilin Province by using ＇ R＇ Language, and found that a very weak correlation existed between the two aspects. Besides, a certain degree of synchronization existed between the two aspects in different periods by using quadrant diagram method. Most of the city＇s efficiency would be increased when the compact degree was promoted, and the decrease of the compactness was not necessarily effective to decrease the urban efficiency.
