Explore The Scientific Character Of Economics Caused By Sraffa's Production Of Commodities By Means Of Commodities

Piero Sraffa brought forward"criterion of commodity"in Production of commo- dities by means of commodities, attempting back to classical economics system in which the labor theory of value was hard core. He turned a blind eye to the distinct progress by marginal analytical method, and regarded"marginal analytical method"as untruthful. Neo-Cambridge School reconsidered Keynesianism according as Piero Sraffa's theory, and then it aroused controversy. In the issue, Neo-Cambridge School was washed out.In the twentieth century, there were several controversies that impacted strongly on economics. Why did they happen even in twentieth century? It's a weighty question and should be solved by dint of philosophy about knowledge. Research has shown that the prime causation is that economist couldn't resolve the question what the scientific economics is. What is more, they diverged what the scientific social science is.We can see that there have been some transformations in the history of economics. For one thing, researches on axiology changed. In the next place, the purpose of economics had been transformed. Thirdly, economics system had been remodel. We demand an investigation into the matter in order to build stability into economics and supervise effectively economic development.How to assess that a theory is scientific, especially social theory? It's a indis- pensable issue when human enter into 21th century。Sraffa attempted to solve the conception of classical economics system. The instance indicated he knew the unsci- entific factor in the classical economics system. But he couldn't do it.We explore"Sraffa phenomenon",not only to preach to the flooding unscientific study as yet, but also to probe into social science's scientific character and reinterpret the scientific criterion.
