Sectoral Allocation of Labor Force with Development and the Effect of Trade Activity
研究了贸易活动的规模和性质如何影响劳动力从农业向制造业再向服务业转移的过程，基于68个国家的截面数据，发现部门劳动力份额与人均GNP的关系随进口规模和进出口结构而变化。
There has been considerable uniformity noted across nations in the tendency of the labor force share in agriculture to fall and that in manufacturing to first rise and then fall. At the same time, the relationship between sectoral labor force shares and development has shown a definite contextual variation. This paper investigates how the size and nature of trade activity impacts upon the labor force transformation. The analysis is based upon Casetti's Expansion Method, and uses cross-sectional data from sixty-eight countries. Results indicate that the relationship between sectoral labor force shares and per capita GNP varies with the relative size of a country's imports as well as the composition of its exports and imports.
