Involution of Traditional Agriculture:Internal Mechanism and Bordered Condition;

The traditional agriculture of involution is characterized by its marginal decrease of labor productivity.

Experimental studies on the densification process of pure and admixed lubricated iron powders were explored with an Instron thermal simulation tester.

The effects of TiC content,composition of the binder phase and reactive hot pressing processes on densification process and mechanical properties were studied.

And the addition of Ni significantly improves the densification process by enhancing matter transfer in the binder phase.

In this paper,the authors raise a new theoretical hypothesis called institutional involution.

It provides a starting point for the system construction and avoidance the institutional involution.

After involutionary hypothesis has been put forward, three kinds of responses have come into being in the world of academy in China, among which the digital analysis school argues that the family income and the living standards of farmers are the judging criteria.
