Schumpeter and Georgescu-Roegen on the foundations of an evolutionary analysis
重新审视熊彼特和乔治斯库-罗根的重要贡献，指出他们以质性变化为核心，论证了演化分析为何必须采用多样化的非正式方法，以及如何与现代静态和动态分析互补，并将环境问题纳入演化经济学议程。
Qualitative change is widely recognised as a defining feature of evolution. Schumpeter and Georgescu-Roegen put it at the centre of their methodological reasoning. I revisit important contributions of these two authors, paying attention to the immediate relationship of the major traits and treated issues between their works. With reference to qualitative change, their joint approach provides answers as to (i) why an evolutionary analysis has to necessarily apply a varied less formal set of methods as compared with modern static and dynamic analysis, (ii) why an evolutionary analysis is a necessary component of economic analysis and (iii) how it can be seen as complementary to modern statics and dynamics. They argued for methodological pluralism, where the choice of methods shall derive from close observation of the subject matter under scrutiny. Georgescu-Roegen’s reasoning shows the necessity of interdisciplinary contributions and the interrelation of economic activity and environmental impact and constraints, putting environmental issues immediately on the evolutionary economics agenda. The paper provides a new ground for evaluating Georgescu-Roegen’s own and their joint contribution to modern research.
