摘要
基于考虑非期望产出的全局SBM模型,对2006-2019年我国11个沿海地区碳排放约束下的海洋经济效率进行测度,并分析效率的时空演进情况。研究结果表明:(1)从时间维度来看,我国碳排放约束下的海洋经济效率在2006-2019年整体呈“U”形趋势变动,在2016年之后进入快速增长的时期,2019年达到14年间的最高水平;(2)从空间维度来看,效率在地区间发展极不均衡,总体呈现“南高北低”的分布特征,广东、上海、江苏等南方地区处于效率最高的梯队,北方地区多处于中低效率的梯队;(3)“十三五”时期,我国海洋经济已开始进入由劳动、资本、能源等要素高投入和二氧化碳过度排放的“粗放”模式向“节约集约”模式快速转变的时期。最后,结合我国发展实际,提出提高我国碳排放约束下海洋经济效率的启示。
Based on the global SBM model considering unexpected output,this paper measures the marine economic efficiency under the carbon emission constraints of 11 coastal areas in China from 2006 to 2019,and analyzes the space-time evolution of efficiency.The research results show that:(1)From the time dimension,China's marine economic efficiency under carbon emission constraints showed a"U-shaped"trend in 2006-2019,entered a period of rapid growth after 2016,and reached the highest level in 2019 over the 14-year span;(2)From the spatial dimension,the development of efficiency among regions is extremely uneven,showing an overall distribution characteristics of"high in the south and low in the north".Southern regions like Guangdong,Shanghai,and Jiangsu are in the highest efficiency echelon,while the northern regions are mostly in the middle and low efficiency echelon;(3)During the 13th Five Year Plan period,China's marine economy has entered a period of rapid transformation from the"extensive"model of high input of labor,capital,energy,and other factors,along with excessive carbon dioxide emissions,to the"intensive conservation"model.Finally,combined with the actual development of China,the paper puts forward the enlightenment of improving the marine economic efficiency under the constraint of carbon emissions in China.
