Paper1周婧婕 Does environmental regulation drive specialization in green innovation?

摘要:We examine the response of technological change to one of the major environmental regulations in the European Union (EU)the Ambient Air Quality Directive (AAQD). Our identification strategy exploits the structure of this directive, which imposes air quality measures in regions exceeding pollutant concentration limits. We implement a quasi difference-in-differences strategy and test for the effect of environmental measures on innovation in 654 technology classes at the EU region (NUTS-2) level over the 19992015 period. We show that AAQD environmental measures drive the specialization of regions in green technologies. We find a positive effect for patents in the two most prevailing green technology classes, i.e., clean energy and industrial processes, as well as evidence of spatial leakage.

Paper2管泓旭 全球化背景下中国碳市场的减排和福利效应

摘要:本文提出并建立了在全球化背景下囊括能源市场和碳减排的多地区多行业的一般均衡模型,将生产中能源的使用、碳排放、碳税、碳关税以及全球生产网络纳入模型,为在全球化背景下量化研究低碳政策的福利和排放效应奠定方法基础。本文利用结构式方法估计了模型的主要参数,量化研究了中国建立碳排放权交易系统和欧盟实施“碳边境调节机制”对中国和世界主要经济体的经济和碳排放的影响,并提出了新颖的渠道分解方法。 结果表明中国实施碳市场可以降低中国碳排放、优化产业结构,但将通过降低出口竞争力为中国带来一定的福利损失。由于存在碳泄漏问题,中国实施碳市场对全球碳排放的降低影响有限。欧盟实施“碳边境调节机制”将对中国出口带来一定负面影响,但影响程度有限,对全球碳减排贡献有限。
