总体看,我国对非洲重点能源国家的投资效率不高,仅对少数国家投资效率达到有效水平,对多数国家投资效率则处于中低水平,但对多数能源国家投资规模收益处于递增阶段,显示投资潜力巨大。我国应因地制宜实施投资规模调整策略,打造一体化能源投资产业链,加强油气基础设施和管网建设,共建能源安全利益共同体,以提高对非能源投资效率。 Overall, China’s investment in Africa’s key energy countries is not efficient. Only in a few countries have investment rates reaching an effective level. For most countries, investment efficiency has been at a low level. However, the return on investment of most energy countries is on an increasing scale. Great potential. China should implement measures to adjust the investment scale according to local conditions, build an integrated energy investment industrial chain, strengthen the construction of oil and gas infrastructure and pipelines, and build a community of energy and security interests so as to improve the efficiency of non-energy investment.
