Steven Ng-Sheong Cheung (; born December 1, 1935) is a Hong-Kong-born American economist who specializes in the fields of transaction costs and property rights, following the approach of new institutional economics. He achieved his public fame with an economic analysis on China open-door policy after the 1980s. In his studies of economics, he focuses on economic explanation that is based on real world observation (an observation first approach). He is also the first to introduce concepts from the Chicago School of Economics, especially price theory, into China. In 2016, Cheung claimed to have written “1,500 articles and 20 books in Chinese” during his academic career.He obtained his PhD in economics from UCLA, where his teachers were the American economists Armen Alchian and Jack Hirshleifer. He taught in the Department of Economics at the University of Washington from 1969 to 1982, and then at the University of Hong Kong from 1982 to 2000. During this period, Cheung reformed the syllabus of Hong Kong’s A-level Economics examination, adding the concepts of the postulate of constrained maximization, methodology, transaction cost and property right, most of which originate from the theories of the Chicago school.
