中文摘要 | 本研究利用產出投入概念的線性規劃方式估計中國大陸三十個省分從1996到2003年間的整體績效表現及二氧化硫(SO2)減排的影子價格。產出面包含衡量國家總體產出的國內生產毛額(GDP)及二氧化硫的排放量,投入項目爲資本及勞動,並將所有省分區分爲三大區:東部、中部及西部區域以進行分析比較。研究結果發現:觀察期間,以平均而言,東部的效率表現最佳,而中部的效率表現最需改善;酸雨較爲嚴重的省分其效率表現高於整個國家的平均值。關於影子價格,亦即處理二氧化硫所需的邊際成本,西部的平圴影子價格最高而中部的影子價格最低;酸雨較爲嚴重的省分其影子價格低於整個國家的平均值。故,中國大陸減少二氧化硫的排放確實是刻不容緩之事。 |
英文摘要 | We use the linear programming approach to compute the overall macroeconomic performance and shadow prices of SO2 emission abatements for thirty regions in China during the 1996-2003 period. Our major findings are as follows: On average, the east area is the most efficient and the central area is the most inefficient during these eight years. The average efficiency of those regions with serious acid rain is higher than the others. Shadow price in the west area is the highest, but it is the lowest in the central area. Shadow prices of the regions with serious acid rain are significantly lower than others, implying that the Chinese government should improve the SO2 emission abatement problem in these regions. |
