Data and Code for: China’s Nationwide CO2 Emissions Trading System: A General Equilibrium Assessment

China’s CO2 emissions trading system, the world's largest, aims to significantly reduce CO2 emissions. The system is a tradable performance standard (TPS), differing from cap and trade (C&amp;T). We provide a dynamic general equilibrium assessment that uniquely considers institutional and fiscal features of China that affect policy costs and distributional impacts. Key findings: the TPS's environmental benefits exceed its costs by a factor of five or more. Interactions with the fiscal system reduce or eliminate the TPS's cost disadvantage relative to C&amp;T. Introducing auctioning as a complementary source of allowance supply can reduce costs by 30%.<br>

作为全球规模最大的碳排放权交易体系，中国碳排放权交易系统旨在大幅削减二氧化碳排放量。该体系采用可交易绩效标准（Tradable Performance Standard, TPS），与总量管制与交易（Cap and Trade, C&T）模式存在本质区别。本研究开展了一项动态一般均衡评估，该评估首次纳入了影响政策成本与分配效应的中国制度与财政特征。核心研究结论显示：可交易绩效标准（TPS）的环境收益较其政策成本高出五倍及以上；与财政体系的交互作用可削弱乃至消除TPS相较于C&T的成本劣势；引入拍卖机制作为配额供应的补充来源，可将政策成本降低30%。

本研究附带的数据集与代码涵盖了生成动态一般均衡模型输入数据，以及开展本研究相关模拟实验所需的各类资源。
