改革开放以来，中国经济高速增长，但与其他中高收入国家相比，中国服务业的发展相对滞后。同时，由于户籍制度等限制人口迁移的政策，中国的城市化水平也远远低于同等收入国家。本课题从中国服务业发展滞后和城市化进程缓慢并存的现象出发，通过建立理论模型，研究城市化影响服务业比重的作用机制，并进一步分析城市化对要素收入分配的影响。同时利用中国家庭层面数据、中国跨地区数据及跨国数据，实证分析城市化对服务业发展和要素收入分配的影响。本课题有助于加深对中国城市化进程带来的影响的理解，为中国推进城市化进程提供更进一步的理论论据。相对于国内外已有的研究，本课题的创新之处在于：①构建关于市场规模和产业结构的理论模型，研究城市化影响产业结构的作用机制；②将城市化和产业结构变化结合起来分析劳动收入份额的变动。

Since the economic reform and open-door policy started in 1978，China has experienced remarkable economic growth. However, the service share of GDP in China is low, compared to that in other upper-middle-income countries. Meanwhile, because of migration restrictions, such as household registration system, China is characterized by a low level of urbanization. Based on the above facts, this project develops a theoretical model to investigate the underlying mechanisms through which urbanization affects industrial structure, and to further analyze the impact of urbanization on factor income distribution. Using Chinese urban household-level survey data, city-level data and country-level data, this project empirically examines the effects of urbanization on service share and factor income distribution. This project contributes to a better understanding of the impact of urbanization and provides further evidence for China to advance urbanization. The contribution of this project is two-folded. Firstly, it provides a theoretical model relating market size and industrial structure and sheds light on mechanisms through which urbanization affects industrial structure. Secondly, this study analyzes the changes in labor income share incorporating urbanization and the changes in industrial structure.
