本文以非平衡增长两部门模型为基准模型，通过劳动生产率的差异度量非平衡性，进而研究部门劳动力份额变动趋势和部门对经济增长的贡献率。研究发现，保持两部门产出相对不变，劳动力从劳动生产率较高的制造业转移到相对滞后或渐近滞后的服务业，服务业劳动力份额逐渐提高，对经济增长的贡献率逐渐上升。利用变参数的状态空间模型识别劳动份额提高对经济增长贡献率影响的结构变化，说明劳动力份额的增长正向影响服务业对经济增长的贡献率，且这种正向影响随劳动力份额上升而提高，服务业在经济增长中的滞后效应显著。

This paper base on the benchmark model named unbalanced growth model including two sectors where the difference of labor productivity between sectors measures the unbalance. We illustrate how sector＇s share of labor influence ones contribution to economy growth. If the ratio of outputs of the two sectors is held constant, then the labor force will transfer from the higher productivity of manufacturing to the non-progressive or asymptotic lag sector of service, and the labor force share of service will increase gradually. As the labor force share goes up, the share of service industry＇s contribution to economic growth increasing continuously.
