The link of government procurement services of public officials into private or public companies is very vulnerable to causing bureaucratic corruption. Therefore many countries are constantly revising and perfecting the procurement law so as to prevent corruption. This paper compares the government procurement laws and related ordinances between China and South Korea. In order to achieve this goal, we investigate the differences between the two countries based on the five aspects: basic theory divided into purpose, definitions and scope; incentives to encouragement and bonus; procurement details in the area of quality management, statistics, derivatives trading, contract, price payment, and fines for negligence, etc.; stockpile commodities; and supervision link composed of questions and complaints, and legal liability instructions. Through a comparative analysis, we found four major differences in the aspects of incentives, procurement ways, legal description or specific implementation details, stockpile commodities, and supervision link, except for the basic theory. Therefore this paper have made four policy suggestions: improving incentive system; making obvious legal instructions; introducing derivatives trading including diversified procurement methods; and improving the system of fees and fines. The aim of this article is to absorb the advantages of the Korean government procurement law so as to make useful suggestions for the Chinese government, and therefore revise the government procurement law of China.
