Using an institutional perspective, this paper explores coexisting job search methods in reforming China. Analysis of the 2003 Chinese General Social Survey data shows that China's labour markets are segmented into institutional niches by two key factors: the type of ownership of work organization and the status of the work organization in the market. The effectiveness of job search methods varies across the different institutional niches. Hierarchical arrangements and social networks remain powerful means of obtaining jobs in the state sector, including both monopolistic and competitive work organizations, while job searches using a market-oriented method are comparatively useful for winning jobs in the non-state sector irrespective of whether organizations are competitive or monopolistic in terms of market competition. This paper not only illustrates the value of an institutional approach to labour market research but also reveals the scope of market penetration in China's emerging labour markets.
