基于CHIPS数据,采用代际流动指数和MLM模型实证分析了行业垄断对代际职业流动的影响及其作用机制。研究发现:行业垄断加剧了劳动力市场的行业和职业分割,父代处于低端职业的子代很难流入高端职业,但高端职业内部的代际流动性较强;行业垄断对代际职业流动的直接阻碍效应会随着经济发展而逐步减小;行业垄断通过代际行业传承间接阻碍了代际职业流动,这种间接的阻碍作用会随着经济发展而缓慢减小。
Based on the CHIPS data, this paper uses intergenerational liquidity index and MLM model to empirically analyze the impact of industry monopoly on intergenerational mobility and its mechanism. The study found that: industry monopoly aggravates the labor market and occupational segmentation, the offspring of the low-end generation of parents is difficult to flow into the high-end occupations, but high-end occupational mobility within the intergenerational strong; industry monopoly of intergenerational mobility The direct obstruction effect will gradually decrease with the development of economy; the monopoly of industry indirectly hinders the intergenerational occupation flow through inheritance in the intergenerational industry, and this indirect obstruction will slowly decrease with economic development.
