English Title Of Master Thesis

In this paper, we focus on three problems below: Firstly, what are the reasons for scientific research contract's high enforcement rate?; Secondly, does the high enforcement rate of scientific research contract equate the high efficiency of scientific research? Furthermore, what are the main factors that affect achievement of scientific research from the point of view of principle-agent theory; Finally, what are the main defects of the institution of scientific research contract, and what is our evidence?We analyze the traits of vague contract and the nature of incomplete contract by means of contractual theory. And we deliberate the operate mechanism of the institution of scientific research contract by means of principal-agent theory. Then, we discuss the defects of the institution of scientific research contract by means of public choice theory and statistics.At last, we expound the reasons of scientific research contract's inconceivable high enforcement rate, and find out that the high enforcement rate of scientific research contract does not mean high efficiency of scientific research. As a matter of fact, in the existing framework of institution of scientific research contract, the objectives and behaviors of scientists are distorted seriously, and engender negative influence.
