针对不同区域实行“共同而又有区别”的污染治理政策是实现区域联防治理大气污染的有效措施,而随着省际贸易加强,难免导致污染物在不同区域间的转移。本文采用区域间投入产出模型,对中国30省区间省际贸易隐含PM_(2.5)进行核算。结果表明,省际贸易隐含PM_(2.5)约占总PM_(2.5)排放的1/3,经济危机使得省际贸易隐含PM_(2.5)量变小,但贸易隐含PM_(2.5)在以生产计算的PM_(2.5)排放中的作用在增大。东部省区的省际调出贸易隐含PM_(2.5)主要由最终消费部分导致,而中、西、东北省区则主要为中间投入部分导致,在控制贸易隐含排放时,需对不同调出类型省区采用不同的控制方法。省际调入贸易隐含PM_(2.5)主要由中间投入过程贸易隐含PM_(2.5)构成,越来越多的产品在不同省区间共同生产完成,区域联合治污显得尤为必要。东北、西部、中部省区由固定资本形成导致的省际贸易隐含PM_(2.5)比例要高于东部省区,可见政策导向也是造成贸易隐含排放的原因之一。需重点控制省际贸易隐含PM_(2.5)排放量较高建筑业、机械设备制造业和其他服务业。除河北、山东外,东部省区均为省际贸易隐含PM_(2.5)净调入省份,中、西部、东北省区中则多为省际贸易隐含PM_(2.5)净调出省份。经济危机使得省际间净贸易隐含PM_(2.5)的转移量变小,但并未改变其转移趋势。净调入省区需相应的补偿净调出省区,或对其进行技术转移。
The implementation of “common but differentiated” pollution control policies for different regions is an effective measure to realize regional joint prevention and control of air pollution. With the enhancement of inter-provincial trade, it will inevitably lead to the transfer of pollutants in different regions. This paper uses the inter-region input-output model to calculate the implied PM_ (2.5) of inter-provincial trade in China’s 30 provinces. The results show that the implicit PM 2.5 of interprovincial trade accounts for about 1/3 of the total PM 2.5 discharge and the implosion of PM 2.5 is less than the implosion of trade implosion due to the economic crisis. However, The effect in the calculated PM 2.5 emission is increasing. The implicit PM_ (2.5) of inter-provincial transfer in eastern provinces is mainly caused by the final consumption while that of central, western and northeastern provinces is mainly caused by the intermediate input. In controlling trade implicit emissions, Different types of provinces using different control methods. The inter-provincial trade implied PM 2.5 mainly consists of the implicit process PM_ (2.5) in the intermediate input process, and more and more products are co-produced in different provinces and regions. It is especially necessary for the regional joint pollution control. The implication of inter-provincial trade in Northeast, West and Central provinces resulting from fixed capital implies that the ratio of PM 2.5 is higher than that in the eastern provinces and autonomous regions. Therefore, policy orientation is also one of the reasons for implicit trade emissions. Need to focus on inter-provincial trade Implied PM_ (2.5) Higher emissions of construction, machinery and equipment manufacturing and other service industries. Except for Hebei and Shandong, the eastern provinces and autonomous regions all implied the net importation of provincial PM_ (2.5) provinces, while the middle and western provinces and northeastern provinces were mostly net imputed PM_ (2.5) provinces of interprovincial trade. The economic crisis made the transference of implicit PM_ (2.5) among the inter-provincial net trade smaller, but did not change its transfer trend. Net transferred to the provinces and autonomous regions need a corresponding net compensation transferred out of the province, or its technology transfer.
