  报告人简介:

  杨自力教授是纽约州立大学宾汉顿分校经济学教授、12BET兼职教授、耶鲁大学经济学博士,主要从事资源与环境经济学、能源经济学、经济建模、应用博弈论、中国经济等研究工作。他与2018年诺贝尔经济科学奖获得者耶鲁大学教授William D. Nordhaus合作,发展建立了在世界范围内最具影响力的气候变化综合评估模型(RICE),他们两人的合作论文发表在American Economic Review(这是Nordhaus获得诺奖的两篇核心论著之一)。RICE模型及其衍生的多个模型在联合国政府间气候变化专门委员会(IPCC)历次报告中被广泛使用。杨教授还独立发展了将博弈论数值解的概念和算法与气候经济综合评估模型相结合的研究方法,在此开拓性领域居国际领先地位;是世界上第一个将非合作博弈解以及合作博弈解引入大型综合评估模型的学者;是上世纪90年代麻省理工学院能源实验室EPPA模型的最主要建模者;著有 "Strategic Bargaining and Cooperation in Greenhouse Gas Mitigations: An Integrated Assessment Modeling Approach"(MIT 出版社)。

  报告内容摘要:

  In this paper, we study “phototaxis” of socio-economic indicators in the spatial setting. Different from the conventional spatial econometric approach, we use geographic information to inference statistical connections among spatial variables directly. We proved a proposition stating that if two spatial variables’ gravity centers are close and their respective autocorrelation coefficients (Moran’s I) are high, then the correlation coefficient between these two variables is high. In other words, a sufficient condition in geographical characteristics of the concerned variables guarantees their statistical inference. We use remote sensing data of the nightlight and the GIS data of four socio-economic indicators from 18 cities in the U.S. to test such relationship empirically. The data supports the conclusion of the proposition. The novel approach in this research might be useful to the application of GIS in economic analysis and policy formation.
