服务业生产效率异质性对城乡收入差距影响研究

Empirical Study on the Impacts of Productivity Heterogeneity in Chinese Service Industry on the Urban-rural Income Gap

城乡居民收入差距问题已成为目前的研究热点。从行业间生产效率差异的角度出发,运用序列DEA-Malmquist全要素生产效率指数法测算1994年至2011年中国服务业分行业的全要素生产效率发展水平的差异程度,考察行业间发展不均衡对城乡居民收入差距所造成的影响。研究结果表明,在1993年至2002年和2004年至2011年,细分行业全要素生产效率异质性、技术效率异质性与城乡收入差距呈正相关关系,技术进步水平的异质性与城乡收入差距没有表现出显著的相关性。研究结论可对未来进一步探索提供有益的借鉴。

As the income gap of urban-rural residents is becoming a research hotspot, this paper measures tbe development heter- ogeneity level of total factor productivity （TFP） of Chinese service sub-industries from 1994 to 2011 by sequential DEA- Malmquist TFP index from the perspective of productivity differences. The researchers also explore the impacts of sub-industries development heterogeneity on the income distribution of urban-rural residents. Results show that both sub-industries TFP develop- ment heterogeneity and technological efficiency heterogeneity have positive relationships with urban-rural income gap, which is not significantly related to technology progress heterogeneity. This study may provide beneficial references for the future research.
