摘要:

当各地区减排成本增速高于经济增速时,单一碳排放效率指标已无法完整刻画减排情况。本文基于全局非径向方向性距离函数(Global NDDF)及其对偶原理测算得出2010—2015年中国全要素碳排放效率总体呈上升趋势,其中东部地区效率最高,而东北与西部地区效率最低;全国各地区总的碳减排成本增长率与经济增速比值呈波动上升趋势,且大部分地区总减排成本增速大于经济增速。这表明碳排放效率提升是以高于经济增速的减排成本投入实现的。数理推导结论表明,解决减排成本增速远超GDP增速的困境,需满足碳影子价格增速小于碳生产率增速。计量模型进一步证明,中国碳影子价格增长速度高于碳生产率增速导致了减排成本增速快于经济增速的困境。为解决这一问题,应以多元指标体系替代单一的碳排放效率指标,全面衡量减排能力;构建全国碳交易市场以缓解各地区碳影子价格异质性现象;持续推动结构性改革和产业结构转型升级,提高能源利用效率。

Abstract:

When the abatement cost growth rate is higher than the economic growth rate, the single carbon emission efficiency index cannot depict the situation of emission abatement. Based on the global non-radial directional distance function (Global NDDF) and its duality principle, the global carbon emissions productivity in China is calculated. For the sample period 2010-2015, the national GCP is in upward trend, with the eastern region having the highest GCP, the northeast and western regions having the lowest; The ratios of abatement cost growth to GDP growth of the provincial administration regions in China rise in volatility, and the abatement cost grows faster than GDP in most regions. This means the carbon efficiency improvement is achieved by the rapid growth of abatement cost, which is higher than the GDP growth. The mathematical deduction shows that the condition to solve the dilemma of abatement cost growth exceeding GDP growth means the growth rate of carbon shadow price is lower than the growth rate of carbon productivity. Empirical results prove further that the overgrowth of carbon productivity by carbon shadow price leads to the dilemma of abatement cost growth exceeding GDP growth in China. Therefore, China should replace the single carbon emission efficiency index by a multiple index system to measure the capacity of abatement in an all-round way; The national carbon trading market should be built to alleviate the heterogeneity of carbon shadow price in different regions; And government should promote structural reform and improve energy efficiency.
