社会传统和市场机制共同作用影响中国社会经济发展路径。本课题以北京大学"中国家庭动态跟踪调查（CFPS）"数据为基础，研究不同市场化环境下，社会资本对中国阶层流动性（包括跨代教育、职业阶层流动和当代收入阶层流动）的影响。主要内容如下：（1）整理2008年以来历年CFPS数据；在CFPS抽样范围内，补充调研相关社区层面数据，并构建社会资本和省市县层面的市场化程度指标体系。（2）基于CFPS数据配对父母-子女关系，在不同市场化环境下，从教育、职业两个层面研究社会资本对代际阶层流动性的影响。（3）不同市场化环境下，对比人力资本和劳动时间，建立合适的分解模型，用分位回归和反事实分析研究社会资本对于不同收入阶层的差异化回报。（4）以面板数据为基础，研究不同市场化环境下，社会资本对收入阶层流动的影响。（5）基于阶层流动性的视角研究社会传统与市场化的合理边际，评估中国未来代际阶层流动和收入流动问题。

Based on the Chinese Family Panel Studies (CFPS) datasets, this project study on the mechanism that social capital affects class mobility in China, including intergeneration education and profession mobility and income class mobility, under different marketization degree. We focus on the following five aspects: (1) Clean the CFPS datasets since 2008. In addition, we will launch relative surveys at the community level according to the sample of CFPS data. Base on these data, we try to conduct a system of index like the marketization degree indicator and the social capital indicator at the province, city and county level respectively. (2) Match the relationship between parents and children in terms of household data of CFPS, and discuss the effect of social capital on intergenerational class mobility in the dimension of education and profession under different marketization degree. (3) Model how return of social capital to different income class varies under different marketization degree using quantile regression and counterfactual analysis. (4) Conduct a panel model to study on how social capital affects the mobility of different income classes when marketization degree varies. We will also test the robustness of our conclusion using different proxies and changing test methods. (5) Evaluation on the issue of intergeneration class mobility and income mobility in future China.
