The Economy-Carbon Nexus in China: A Multi-Regional Input-Output Analysis of the Influence of Sectoral and Regional Development

Abstract

China has become the world's largest carbon dioxide (CO 2 ) emitter. Sectoral production activities promote economic development while also adding considerably to national CO 2 emissions. Due to their different sectoral structures, each region shows different levels of economic development and CO 2 emissions. The Chinese government hopes to achieve the dual objectives of economic growth and CO 2 emissions reduction by encouraging those sectors that have high economic influence and low environmental influence. Based on the above background, this study constructed an inter-regional sectoral economic influence coefficient (REIC) and a CO 2 emissions influence coefficient (RCIC) based on the basic multi-regional input-output (MRIO) model to analyse the economy-carbon nexus of 17 sectors in 30 regions in China in 2010. The results showed that most Chinese sectors and regions had low CO 2 emissions influences in 2010. However, some sectors showed negative environmental influences. Specifically, the mining-related sectors showed high CO 2 emissions influence with low economic influence. It is encouraging that some light industry and high-end equipment manufacturing sectors had low CO 2 emissions influence with high economic influence. For regions, geographic location and past preferential policies are the most important factors influencing local economic growth and CO 2 emissions reduction. Most inland regions have low economic influence with high or low CO 2 emissions influence. Meanwhile, most coastal regions showed high economic influence with low CO 2 emissions influence. Finally, we propose some policy implications for sectors and regions.

Performance of solar hot-water installations from roof-constructed solar collectors integrated with a central heating supply for tobacco curing

“…Increasing the collecting area using idle land close to the curing barn groups can also directly increase the proportion of solar energy available for curing in the resource-rich regions. On the thermal efficiency of the solar-self collector with hot water, the collection efficiencies above 94% have recently been achieved by [16]. Many environmental policies that encourage use of solar energy have been issued by the government [4].…”

Nexus Strength: A Novel Metric for Assessing the Global Resource Nexus

“…More recently, and in the context of the increasing importance of inter‐regional and international trade, nexus studies applied MRIO (Miller and Blair ; Duchin and Steenge ) and ecological network analysis (Fath and Patten ) to explore structural properties and sectorial interactions of extended economic systems (Guo and Shen ; Wang and Chen ; Duan and Chen ; White et al. ; Yan and Ge ).…”

Total-Factor Energy Efficiency (TFEE) Evaluation on Thermal Power Industry with DEA, Malmquist and Multiple Regression Techniques

“…For example, Yan and Ge proved that the increasing GDP could accelerate the development of power generation industry, e.g., the installed capacity and the generating capacity [20]. The dual influencing relationships between economy development and power industry will stimulate the efficiency enhancement.…”

“…Lina et al, calculated the energy return on investment (EROI) by a mixed physical and monetary approach in order to redefine and evaluate the EROI for the national economy [19]. From the relationship between economy and carbon, Yan and Ge assessed the sectoral and regional development by input and output analysis [20]. They found that geographic location and past preferential policies were the most important factors influencing the local economic growth and CO2 emissions reduction.…”
