摘要
This paper systematically presents a survey of the empirical literature studying the embodied CO2 emissions China's foreign trade (ECCT). Based on the bibliometric method and the online version of SCience Citation Index-Expanded (SCI-E) and Social Sciences Citation Index (SSCI), this study summarizes the late, publications regarding ECCT in peer-reviewed journals in terms of quantities, most productive countries institutions, authors, citations, 'and disciplines. By using synthetic analysis of keyword frequency, this stud!, reveals the most popular methodologies applied in measuring ECCT, discusses the variation of numerical result: in the literature, and reasons and countermeasures for the results uncertainties. Continuous investigation of thc, literature releases the methodology employed for measuring ECCT becoming more reasonable and the result more critical. However, the numerical results of ECCT are of great discrepancies within given year by differen considerations on methodology specification, accounting principles, and data sources and processing. Foi instance, the estimates of CO2 embodied in China's exports changed from 478 Mt to over 3000 Mt and those in China's imports ranged from 140 Mt to over 1700 Mt in 2007. Therefore, overcoming data inheren limitations and reducing discrepancies among available databases should be urgently considered. The result: imply that the prospective research tendencies on ECCT are to (1) improve China's regional input-output datt and energy intensity data to more precise estimates under global perspective; (2) estimate China's carbon emission at firm level by different firm ownerships in production and consumption worldwide; (3) asses China's carbon emission from processing or non-processing trade by compiling more detailed multi-regiona input-output table; (4) evaluate city level carbon mitigation capacity in China under global MRIO model; (5) explore new carbon management experience in China's carbon trading market and new trade expansion polio; of 'one belt and one road' in her new growth era.
