Abstract Non-observed economy (NOE) has many effects on economic growth, but the impact on income inequality has not aroused much attention. Based on the labor remuneration model of dynamic equilibrium solution, this paper holds: with the expansion of NOE size, the relative wage of NOE sector (income inequality) experiences monotonically increasing, but the rate of marginal change firstly increases and then decreases. When considering the stochastic dynamic adjustment factor of workers’ decisions, the size of NOE and income inequality have the high and the low dynamic equilibrium points. The labor remuneration model of NOE sector is supported by the empirical test for Chinese provincial panel data from 2000 to 2010, which shows that the size of NOE has the significant positive effect on income inequality. At the same time, human capital, marketing degree and corruption level have the positive impact on income inequality, and the urbanization level shows significant negative impacts on income inequality. Based on the empirical results, this paper puts forward corresponding policy and directions for future research.
