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 evaluate the efficiency of China’s telecom industry in 31 provinces and cities in 2005-2009. The total efficiency, technical efficiency and scale efficiency are measured under the condition of constant returns to scale and variable returns on scale. On the basis of this, the levels of economic development, residents’ spending power, and the telecommunications industry’s lifestyles for residents are respectively introduced Impact, technological advancement, price cap regulation and telecom restructuring, Tobit regression is used to explain the three efficiency values respectively. The analysis shows that the level of economic development has a significant positive impact on the overall efficiency value, the consumption level of residents has a weak positive impact on the efficiency value, the impact of the telecommunications industry on the residents’ living efficiency has a negative effect on the overall efficiency value, and the technical progress has a greater technical efficiency Promoting role, the price cap regulation to a certain extent, limited the total efficiency and technical efficiency, structural reorganization of the total efficiency and scale efficiency also have a negative effect.
