Directional spatial spillover effects and driving factors of haze pollution in North China Plain
报告摘要：
Haze pollution is one of the most serious environmental problems in China and wind direction plays a crucial role in the process of pollution transport. Upwind and downwind cities interact with each other differently, so the directions of spillover effects should be emphasized in empirical study. With the panel data of 44 cities in North China Plain from 2013 to 2017, we constructed a novel wind direction weight matrix to analyze the spatial variations of PM2.5 concentration. The matrix was then incorporated into a spatial panel model to quantitatively evaluate the impacts of socioeconomic and natural factors on PM2.5 concentration. We found that wind direction dominates the distribution of PM2.5 concentration. The increase of GDP per capita reduces PM2.5 concentration while the increase of the other socioeconomic factors raises it. Natural factors directly or indirectly affect PM2.5 concentration. Particularly, the spillover effects of socioeconomic factors are greater than their local effects. Therefore, investment of air pollution control in a neighboring area may be more effective than in the local city itself. The mechanism of pollutant transport should be fully considered in the fields such as the construction of urban air ducts, industrial layout, and eco-compensation.

环境质量及其以健康效应为代表的个体福利效应的空间和人群分布的演变及公共政策含义
报告摘要：
环境政策及干预措施涉及主体众多，本研究针对社会经济评估和干预手段的选择而言，关注不同群体的社会经济特征所具有的多样性及其影响的揭示。对于环境质量分布及其变化所带来影响在人群维度的具体表现形式的揭示和分析旨在提供从区域和人群视角对政策情境的刻画，也为构建完善的政策理性的提供必要基础。
