随着中国经济的发展，中国对外援助和政府支持性投资规模日益加大，吸引了国内外政商学界的广泛关注。发展经济学关注外部援助和投资的成效但未达成共识，对其作用机制也未有定论。同时，在“一带一路”战略背景下，能否对当地政治、经济和社会产生积极影响关系到中国的经济利益和国际形象。因此分析中国不同于发达国家传统模式的对外援助和政府支持性投资对当地稳定和发展的影响及其作用机制既补充了发展经济学理论，同时也有较强的政策意义。本项目利用地理信息系统和遥感技术整合的大数据克服传统研究局限，通过计量模型评估是否中国对外援助和政府支持性投资减少了当地的冲突、促进了当地的经济发展，并通过对援助和投资分类解析深入理解其作用机制。在基线模型的基础上，该研究扩展对外援助与投资效果的异质性分析，即其效果在何种自然和社会环境下更为有效促进稳定与发展，据此有针对性的提出政策建议，更有效合理地配置援助与政府支持性投资的资金和人员。

With rapid growth of China's economy, China's foreign aid and government-sponsored investment (FAGSI) has been increasing, drawing a wide range of attention from domestic and foreign politics, business and academia. The literature of development economics has focused on the impact of foreign aid and investment, but failed to reach a consensus on its impact and mechanism. Further, in the background of “one belt, one road” initiative, whether or not China’s FAGSI promoted the polity, economy and society can influence the economic interests and international image of China as well. Thus this research on the effects and mechanism of China's FAGSI, which is different from the traditional pattern of developed countries, contributes to the relevant literature in development economics, and also sheds light on the policy practice. Exploiting the big data integrated with geographic information systems and remote sensing to overcome the limitations of previous studies, this study employs an econometric model to evaluate whether or not China's FAGSI has mitigated local conflicts and promoted economic development. Moreover, a further investigation into the different roles of various types of aid and investment enriches our understanding of its functioning mechanism. Beyond the baseline model, this study will conduct the heterogeneity analysis of the effectiveness of foreign aid and investment, to show under which natural and social conditions the aid and investment are more effective to promote stability and development. The heterogeneity analysis enables us to provide policy recommendations to make more efficient and reasonable allocation of funds and personnel for FAGSI.
