Research On Cost Measurement And Allocation Of Responsibilities In China’s Inter-regional Trade

Forging a strong resilience of sustainable economic development,not only need to release the potential of the domestic super-large market through a smooth and efficient domestic cycle,but also need to solve the outstanding problems of China’s resource and environmental constraints through the transformation of green development,so as to enhance the ability of economy to continuously move towards high-quality development.However,the smooth and free flow of domestic inter-regional trade not only promotes economic circulation,but also provides a transmission mechanism for carbon emissions,which leads to prominent problems such as carbon emissions leakage and unclear rights and responsibilities.Scientifically calculate domestic inter-regional trade costs and their implied environmental costs,then design the allocation of environmental costs to clarify the carbon emission responsibilities of each regional entity can provide important enlightenment for the government to formulate trade facilitation and carbon emission reduction policies considering regional heterogeneity,which is not only an important theoretical issue to smooth the domestic great cycle under the "dual carbon" goal,but also an inevitable requirement for China to achieve a virtuous cycle of national economy at a higher level.Based on value-added trade accounting,this article constructs a real measurement system of inter-regional trade costs and trade implied environmental costs under the division of value chain,uses China’s inter-regional input-output table and carbon emissions inventory data to conduct specific calculations,then analyzes the situation of inter-regional trade implied net carbon transfer and identifies the responsible parties for trade implied carbon.The results show that:(1)The cost of inter-regional trade in China shows a trend of first decreasing and then increasing,with the costs in the Northern coastal region being the largest,while the cost in the Eastern coastal region being the smallest and the largest decline.From the industry perspective,the trade cost in the construction industry is relatively high.The decomposition reveals that the "proximity preference" feature of inter-regional trade has weakened,and trade flows are gradually breaking the constraints of regional space;(2)The implied environmental costs of China’s inter-regional trade shows a trend of first increasing and then decreasing,with the cost in the Eastern coastal region being largest and the largest increase,while the cost in the Northern coastal region being the smallest.From the industry perspective,the environmental cost of the mining and processing industry is relatively high.It is found that each region constitutes the main body of higher environmental cost with the Eastern and Southern coastal regions;(3)From the perspective of the linkage analysis of trade costs and trade implied environmental costs,the Northeast,Eastern coastal,and Southwest regions present a differentiated development trend of two types of costs,while agriculture,forestry,animal husbandry,fishery,and service industries also present similar situations in each region;(4)The scale of implied net carbon transfer in China’s interregional trade has significantly increased,with the Central region,Northern and Eastern coasts consistently showing net carbon outflows,while the Southern and Northwestern consistently showing net carbon inflows.The decomposition shows that inland regions are more likely to generate carbon outflows,and coastal regions are more likely to bear carbon inflows;(5)The Northwest region bears more carbon emission responsibilities,while the Beijing-Tianjin bears a larger proportion of carbon emission.The decomposition shows that each region bears more carbon emission responsibilities in bilateral trade with the Central region,while the Central region benefits less from bilateral trade.
