摘　　要：当前中间品贸易渠道影响企业能源绩效问题的理论和经验证据尚不完善,本文首次从产业间投入产出联系的中间投入品这一新的视角,研究贸易自由化对企业能源消费强度的影响。首先,本文通过构建理论模型,厘清了开放经济条件下中间品关税降低通过提高最终品部门企业生产率和中间品进口效应降低企业能源消费强度的作用机制。其次,利用投入产出表构建中间品行业关税,从微观企业层面展开经验分析,结果表明,中间品关税下降显著降低了企业能源消费强度,并透过企业生产率、进口中间品质量和种类起作用。进一步分析表明,对高能耗、高能源效率和高技术行业企业,中间品关税下降发挥了更大的节能减排效果。因此,中间品关联是贸易自由化促进企业节能减排、提高能源资源利用效率的重要渠道。该结论为全面扩大对外开放,促进企业节能降耗,提高能源绩效和全面绿色转型提供了重要的理论和经验依据。There is no much studies in theoretical and empirical evidence of the impact of intermediate inputs trade on enterprises’energy performance.In this paper,we analyze,at the first time,from the new perspective of inter-industry input-output linkages about the impact of trade liberalization on energy consumption intensity.Firstly,by setting up a theoretical model,we clarify the mechanism by which tariff reduction of intermediate goods under an open economy reduces the energy consumption intensity of enterprises by improving the productivity and the import effect of intermediate in the final product sector.Secondly,the tariffs of intermediate product industry are calculated by way of the input-output table.The Chinese corporate pollution database is used to conduct empirical analysis from the micro-enterprise level.The results show that the decline in tariffs on intermediate goods significantly reduces the energy consumption intensity of enterprises.Further analysis shows that the reduction of tariffs on intermediate goods has played a more significant role in energy conservation and emission reduction for high-tech enterprises with higher energy consumption and energy efficiency.Therefore,the intermediate product linkage is an important channel for trade liberalization to promote the enterprises’energy conservation,emission reduction and to improve energy resource utilization efficiency.This result provides an important theoretical and empirical evidence for further deepening of opening up,promotion of energy conservation and consumption reduction of enterprises,improvement of energy performance and overall green transformation.
