在新技术全球扩散成为推动国际分工系统性重构重要动因的背景下，对技术扩散引起的生产和消费外部性跨境转移及其生态环境效应全球溢出的研究，成为理解经济一体化进程下技术、经济与生态环境的耦合关联，制定利益协调、激励兼容和多方共赢的生态环境治理政策的基础性研究工作。本研究通过综合运用传统技术经济学、国际经济学和生态环境经济学的跨学科分析方法，识别国际分工重构的特征并量化描述其动态过程，构建国际分工下技术扩散的理论模型并阐释其内在机理，解构全球技术扩散的生态环境效应并测度其多尺度影响，评价中国参与国际分工中的生态环境贡献，重点阐释技术扩散与国际分工、经济结构及其生态环境效应之间的深层逻辑，以提供系统性生态环境治理方案。研究成果将完善现有技术要素在全球经济中的均衡理论和基于生态环境影响的技术创新理论，同时为理解当前国际分工重构进程中的技术要素功能，解析和完善生态环境系统治理框架提供理论支撑和政策建议

In the context of the reconstructing processes of international industrial division, which are driven by the new revolution and global diffusion of technology, systematically analyzing the cross-border transfer of externalities caused by production and consumption and quantitatively evaluating the ecological and environmental effects resulted from technology diffusion in global economy becomes fundamental for understanding the connections among technology, economic activity, ecological and environmental effects and for formulating the related polices with benefit coordination, incentive compatibility and multi-win cooperation. By virtue of the interdisciplinary techniques in the fields of technological economics, international economics, ecological and environmental economics, the dynamic processes and typical characteristics for international industrial division would be identified, along with modelling the interior mechanism of technological diffusion under the production segments, measuring the multi-scale ecological and environmental effects which are driven by the global diffusion of technology, and assessing the corresponding contributions with the participation in the global supply chains for China. This project will provide both theoretical contributions and policy implications for understanding the complex functions of technological elements in the international industrial divisions and for upgrading the global ecological and environmental governance.
