CO2 Emission Reduction and the North-South Economic Gap:An Analysis Based on a Quantitative Spatial Model
At the United Nations General Assembly in 2020,Xi Jinping made the official announcement that China will strive to peak carbon dioxide emissions before 2030 and achieve carbon neutrality before 2060.At the same time,China is faced with a daunting task of developing the economy and improving people's livelihood,facing new situations and new problems such as the obvious divergence of regional economic development.In this paper,we construct a multi-regional multi-sector general equilibrium trade model with input-output linkage,labor mobility and CO2 emissions based on Caliendo et al.(2018)to quantify how CO2 emissions peak affects regional economic differences and analysis the role of the national carbon trading market.The main findings are as follows:given the current rate of productivity growth,(1)if there is no national carbon trading market,carbon emis-sion reduction will restrain the economic development of developed regions,and narrow the regional economic gap between North and South;(2)if the national carbon trading market was established,carbon resources would be reallocated from low efficiency regions to high efficiency regions.As a result,the efficiency of carbon resource allocation improves,but will also exacerbate the income gap between the North and the South.There-fore,in the process of achieving carbon emission reduction goals,it is necessary to com-bine central fiscal transfer payments to solve the problem of uneven regional development and reduce the regional economic gap that increases in the process.
