摘要气候法规往往针对能源密集型部门，其产品被广泛用于工业生产作为中间投入，碳减排可能会部分抵消中间投入导致的泄漏。本文旨在从理论和实证两方面研究中间投入关联对碳泄漏的影响。理论部分建立了一个具有投入产出联动结构的Harberg型模型，确定了四种泄漏效应，并导出了这些泄漏效应的封闭解。实证部分建立了中国经济的可计算一般均衡模型，并引入结构分解分析方法将理论模型与实证模型联系起来。当对发电部门实施碳价格时，我们的结果显示了显著的部门碳泄漏。我们的分解分析进一步表明，这种泄漏主要是通过生产替代效应和乘数效应。我们的研究结果强调了在讨论气候政策的碳泄漏问题时部门联系的重要性。
Abstract Climate regulations tend to target energy-intensive sectors whose products are widely used in industrial production as intermediate inputs, and carbon abatement may be partially offset by intermediate input-led leakage. This paper aims to examine the impact of intermediate input linkages on carbon leakage both theoretically and empirically. The theoretical part develops a Harberger-type model with an input-output linkage structure, identifies four leakage effects and derives closed-form solutions for these leakage effects. Its empirical part builds a computable general equilibrium model of China's economy and introduces structural decomposition analysis to link the theoretical and empirical models. When imposing a carbon price on the electricity generation sector, our results show significant sectoral carbon leakage. Our decomposition analysis further suggests that such leakage is mainly through the production substitution effect and the multiplier effect. Our results highlight the importance of sectoral linkage when discussing the carbon leakage issue of climate policies.
