摘　　要：运用因素分解法将辽宁省交通运输业碳排放强度分解为结构份额和效率份额,通过分析辽宁省近十年的统计数据,计算出交通运输业的碳排放强度的结构份额和效率份额.分析数据显示,辽宁省交通运输业碳排放强度的趋势逐年下降.在下降的因素中,结构份额的累计贡献率为51.99%,而效率份额的累计贡献率为48.01%.可见,影响碳排放强度下降因素中结构份额和效率份额的地位几乎同等重要.Carbon emission intensity traffic transportation industry in Liaoning province is decomposed into structure share and efficiency share.Through the analysis of nearly 10 years of statistical data in Liaoning,the structure share and efficiency share of the traffic transportation are obtained downward trend.Among the decreasing factors,the structure of cumulative contribution share is 51.99%,and the efficiency of cumulative share accounts for 48.01%.Visibly,structure share and efficiency share play almost equally important roles.
