区域经济的资源环境载荷与效率

Resource-Environmental Pressure and Efficiency of Regional Economy

阐述了表征区域经济的资源环境压力总量和综合效率的环境载荷和效率指标,并对沈阳市1991～2005年的资源环境载荷和效率进行了实证研究.结果表明:这一期间沈阳市经济的综合资源与环境效率年均提高7.4%,投入端和排放端效率年均分别提高8.1%和11.4%.说明沈阳市单位经济产出造成的综合环境压力(尤其是排放端压力)以较快的速率不断降低,这对于处于高速工业化阶段的沈阳市是一个巨大的成绩.然而,其资源环境载荷在2000年后以11%的年增长率高速上升,总载荷的60%～70%来自排放端,而排放载荷的约85%～97%来自能源消费产生的CO2排放.

The aggregate resource-environmental pressure and efficiency of a regional economy were presented.The resource-environmental pressure and efficiency of Shenyang from 1991 to 2005 were studied empirically.The results showed that the aggregate resource-environmental efficiency of Shenyang＇s economy increased by 7.4% at a year,and its efficiencies on the input and output sides increased by 8.1% and 11.4% at a year,respectively.This means that the environmental pressure（especially on the output side） per unit of economic output decreased at a relatively high speed.This is a great achievement for Shenyang in view of the fact that its economy is at a stage of fast industrialization.However,the environmental pressure increased by 11% at a year after 2000.About 60%～70% of the total pressure is from the output end and about 85%～97% of the output pressure is caused by CO2 emission from energy consumption.
