英文摘要：

The Sverige Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 2016 was awarded jointly to economists Oliver Hart and Bengt Holmstrm for their contributions to contract theory. We review Hart ＇s contributions to incomplete contracts and Holmstrm＇s contributions to complete contracts. Building up the optimal incentive contracts and choosing the suitable allocation of property rights can help safeguard the social division of labor cooperation and thus promote the development of economy. This paper summarizes the academic contributions of Oliver Hart and Bengt Holmstrm in contract theory,and introduces the contributions of contract theory for the development of our society.
