中文摘要：

收入分配差距过大是中国社会发展的难点和热点问题，行业垄断已经成为加剧中国收入分配矛盾的重要原因。为此，本文构建新的垄断一竞争两部门利润分享模型，揭示行业垄断影响收入分配的内在机制，并结合中国的经验数据进行实证分析。研究表明，行业垄断在产品与要素市场中，通过最终产品消费的福利转移、要素的区别定价以及垄断利润在不同就业者之间的非均衡分享导致收入分配差距的扩大；在行业垄断力量对经济干预较多的阶段，收入差距扩大问题较为严重，并且往往表现为劳动总收入的下降。因此，持续提升劳动者收入，保持收入分配的合理化，必须配合行之有效的行政垄断部门改革，打破行业垄断所形成的二元经济结构，降低行业垄断在生产和分配领域中的影响。

英文摘要：

The industrial monopoly＇ s effect on income distribution is a serious problem in China＇ s labor market. This paper builds a two - sector profit sharing model to discuss the industrial monopoly＇ s effect on income distribution from the perspective of product prices and factor prices. The result shows that industrial monopoly would widen income gap, and the monopoly power in both goods market and factors market would have a worse effect than that in the single goods market. Empirical data also shows that when the Monopoly power has more intervention in the economy, the income distribution problem is more serious, and often shows a decline in total labor income. The narrowing of income gap and the growth of total income could not be achieved under the industrial monopoly. The reform of income distribution system depends on the broken of this dual structure of monopoly economy.
