Technological progress greatly contributes to the promotion of carbon productivity (CP). This study aims to identify an appropriate mode of technological progress that increases CP. A data envelopment analysis-based method was used to investigate the impacts of four forms of technological progress under two classifications of CP: the progress of neutral technology (NT) and capital-embodied technology (CET) under a technological source and the progress of energy technology (ET) and carbon technology (CT) under an abatement process. We applied dynamic panel data models to deeply analyze the different impacts of the four forms of technological progress on the CPs of Chinese manufacturing industries from 1995 to 2015. Results show that (1) a change in ET contributes more to the promotion of CP than a change in CT; (2) a change in CET promotes CP more than a change in NT; and (3) the indirect effect of a change in CET on CP through a change in ET and the indirect effect of a change in NT on CP through a change in CT are advantageous. These findings provide important policy implications in promoting technological progress and improving Chinese MIs' CPs. Significant policy measures based on theoretical and empirical conclusions are proposed.
技术进步对提高碳生产力（CP）有很大的促进作用。本研究旨在确定一种适当的技术进步模式，以提高 CP。采用基于数据包络分析（DEA）的方法，在两种 CP 分类下（技术来源下的中性技术（NT）和资本密集型技术（CET），减排过程下的能源技术（ET）和碳技术（CT）），考察了四种技术进步形式的影响。我们应用动态面板数据模型，深入分析了从 1995 年到 2015 年，中国制造业的四种技术进步形式对 CP 的不同影响。结果表明：（1）ET 的变化对 CP 的促进作用大于 CT 的变化；（2）CET 的变化对 CP 的促进作用大于 NT 的变化；（3）CET 的变化通过 ET 的变化对 CP 的间接影响和 NT 的变化通过 CT 的变化对 CP 的间接影响是有利的。这些发现为促进技术进步和提高中国制造业的 CP 提供了重要的政策启示。根据理论和经验结论提出了重要的政策措施。
