| Summary/Abstract |
Large-scale population migration entails changes in productive and consumptive activities, which has enormous implications on the spatial relocation of carbon emissions. This study uses multiple methods to empirically assess the impact of interprovincial population migration of China on its trade-induced carbon transfers from a spatial view over 2002–2012. We constructed two networks of migration and carbon transfers, and based on the analysis of their topological structure, we inferred that carbon flows and migration are complements–larger migration flows typically correlate with larger trade-related carbon flows. Furthermore, we analyzed how migration affects interprovincial carbon transfers; in addition, we explored the geographical factor by dividing Chinese provinces into five subregions. The results illustrated that trade-induced carbon emissions situation in China was shaped partly by interprovincial migration at the national level. While the contribution of migration varies markedly across subregions owing to the unbalanced regional economic development and carbon intensity, migration-focused emission control strategy should be enhanced discriminatively to better understand China's inter-provincial joint energy conservation and emission reduction policy.

| Summary/Abstract |
With an increase in China's oil imports, China's oil supply will also continue to be effected by the socio-economic stability of oil-exporting countries and the safety of oil transport routes. This paper introduces a systematic and quantitative method to evaluate the influence of China's oil import risks (OIR) on the national economy and industrial sectors from a perspective of apply chain process. For this analysis, China's OIR is quantified by integrating oil exporting country risk and the risks from oil transportation routes. Country risk is defined as the oil-exporting country's political risk caused by political changes or internal conflicts. Transport risk is defined as the risk of shipping routes affected by pirate attacks and geopolitics. Second, the relationship between China's OIR and oil import costs is analyzed using a multiple linear approach. Third, an input-output analysis method is used to research the effect of the cost of China's oil imports on the cost of investment within China's domestic sectors. This research finds that the corresponding impact on GDP is 3494.5 million dollars given an increasing by 10% of China's OIR. And the impact on domestic sectors differs from sector to sector. Finally, this paper puts forth recommendations to improve long-term oil supply security in China.
