Abstract

ABSTRACT The aim of the article is to critically analyze Environmentally-Adjusted Multifactor Productivity (EAMP), by considering the Classical-Post-keynesian environmental framework Ecological Macroeconomics, integrated with the Evolutionary Environmental Economics. The paper introduces EAMP as rooted in in neoclassical economics and derived from Cobb-Douglas function with natural resources built by Solow (1974). I present theoretical critiques of EAMP’s neoclassical assumptions by developing perspectives from heterodox Ecological Macroconomics literature. Finally, I discuss the shortcomings of EAMP’s conceptual framework, making specific reference to the policy debate on Porter Hypothesis. The article puts in evidence how the assumptions of constant returns to scale, perfect competition and perfect input substitutability seriously alter the meaning and promise of sustainability policy. The analysis indicates that EAMP is a poor instrument to study complex issues regarding the promotion and effectiveness of green innovations and should therefore be abandoned to face the great challenges regarding the process of ecological transformation.

古典-后凯恩斯主义对新古典环境调整多要素生产率的批判

本文的目的是通过考虑古典-后凯恩斯主义的环境框架生态宏观经济学，结合进化环境经济学，批判性地分析环境调整的多要素生产率(EAMP)。本文介绍了植根于新古典经济学的EAMP，它源于索洛(1974)建立的自然资源的柯布-道格拉斯函数。我通过从非正统生态宏观经济学文献中发展观点，提出了对EAMP新古典主义假设的理论批评。最后，讨论了EAMP概念框架的不足，并具体参考了波特假设的政策辩论。本文论证了规模报酬不变、完全竞争和完全投入可替代性假设如何严重改变可持续政策的意义和承诺。分析表明，在研究绿色创新的促进和有效性等复杂问题时，EAMP是一个较差的工具，因此应该放弃EAMP，面对生态转型过程中的巨大挑战。
