Abstract:

Through the column decomposition of China’s inter-provincial input-output table, this paper calculates the carbon emissions driven by provincial value added and import from the perspective of income-side, and analyzes the carbon emission reduction effects of provincial intermediate trade by using dual Structural Decomposition Analysis (SDA) and counterfactual scenario simulation. The results show that the inter-provincial trade driven by provincial added value and import implies large carbon emissions and carbon transfer during the study period. The carbon emissions cost per unit value added in Beijing-Tianjin region, the eastern coastal region and the southern coastal region are low, and these regions have higher carbon emission efficiency. Provincial value added significantly promotes the increase of provincial carbon emissions; The carbon emission coefficient changes from significant resistance effect to promotion effect; The scale of intermediate trade has promoted the increase of carbon emissions, and the structure of intra-provincial and inter-provincial intermediate trade has gradually shown significant resistance effect since 2012, which has become the main factors to drive provincial carbon emission reduction. From a new perspective of carbon emissions driven by value added, this paper provides a theoretical basis for reducing carbon emissions and achieving carbon neutrality through the adjustment of provincial intermediate trade structure.

Key words: Value added, Intermediate trade, Income-side carbon emissions
