本文基于2011年中国社会状况综合调查数据，运用倾向值匹配方法控制内生性，通过比较非正规就业与正规就业的收入差异厘清既有理论中的认知矛盾。研究发现，非正规就业者总体的小时收入和月收入并未显著低于正规就业者，但该群体存在明显的异质性。由于缺乏正式制度保护，非正规受雇者、特别是女性非正规受雇者存在显著的低收入现象；而非正规自雇者的收入水平显著高于正规就业者，这一收入优势在欠佳的制度环境下还有所放大。因此，二元主义理论和新自由主义理论分别与非正规受雇者和自雇者的特征更为契合。本文认为，两大理论在本质上都追求高效、廉洁、善治的正式制度。对受雇者而言，政府应适度介入，加强劳工的权益保护；而对自雇者而言，政府应继续推进简政放权，改善治理绩效，降低自雇者参与正规经济活动的制度成本。

Based on Chinese Social Survey data 2011, this thesis compare the wage differential between in- formal labor and formal labor via propensity score matching method to clarify the contradiction in existing theories. The research demonstrates the hourly income and monthly income of informal labor aren＇ t signifi- cantly lower than formal labor overall. However, the thesis found heterogeneity in informal labor. For in- stance, the income of informal wage earner, especially for women, is slightly lower than formal wage earner while the hourly income and monthly income of self-employer are significantly higher than informal labor. Additionally, the advantage of self-employer＇ s income magnified when the institutional environment be- come worse. Consequently, dual theory and new liberalism are respectively suitable for informal wage earn- er and self-employer, but both theories are in pursuit of good governance. The government should strength- en labor law for wage earner while streamline administration for self-employer.
