摘　　要：本文使用数据包络分析(DEA)方法对我国2005-2009年31个省市的电信业效率进行了测评。在规模报酬不变和规模报酬可变两种情况下测出总效率值、技术效率值和规模效率值,在此基础上分别引入各地区经济发展水平、居民消费能力、电信业对居民生活的影响、技术进步水平、价格上限规制因素以及电信结构重组等因素,采用Tobit回归分别对三种效率值进行解释。分析发现,经济发展水平对整体效率值有显著正影响,居民消费水平对效率值有微弱的正影响,电信业对居民生活的影响对整体效率值有负作用,技术进步对技术效率有较大促进作用,价格上限规制在一定程度上限制了总效率和技术效率,结构重组对总效率和规模效率也有负作用。This article uses data envelopment analysis （DEA） method to measure the telecom efficiency of China＇s 31 provinces, obtain the overall efficiency, technical efficiency and scale efficiency in the condition which scale returns unchanged and scale returns changed. We use economic development level, consumer ability, important degree of telecoms, technological progress, price cap regulation and restructuring, and also use Tobit model to explain the efficiency. Through empirical analysis, we discover that the economic development level contribute to the improvement of overall efficiency, consumer ability has a negative effect to the efficiency, the technological progress has improved the technical efficiency a lot, and the price cap regulation and restructuring have inhibited the overall efficiency.
