One Occupation, Two Labor Markets: The Case of Longshore Crane Operators
研究码头起重机操作员这一新职业如何因技术变革和劳资博弈分裂为优势与劣势两个劳动力市场，对理解劳动力市场分割和职业形成有参考价值。
Most analyses of labor markets search for uniform patterns across different industries and different occupations, and incorporate variables drawn from either individual skill, worker collective action, or employer strategy theories. This paper is a case study of a single (new) occupation within a single (old) industry-longshore crane operators-using aspects of all these theories. It argues that because the labor market is.the arena of negotiation between firms and workers, analysis should focus on both labor market outcomes and labor market formation. In this case the labor market outcome has been the fragmentation of the occupation into two labor markets, the one providing workers an advantaged status, the other providing workers a disadvantaged status. This is related to technological changes in the industry, and to the conflict among employer goals, union principles, and individual worker interests.
