This paper, based on China's Employer-Employee Match Data (of 2013) as well as OLS ordered prohibit regression analysis made on cash income factors of wage and allowance, and non-wage factors of labor safety and security, tests the wage effect and non-wage effect of collective negotiation. Results of the study show that while the wage effect of collective negotiation is insignificant, the non-wage effect associated with working conditions is significantly positive; and the implementation of collective negotiation, other than employees' wage, did not have significant effect on their revenue, just making considerable improvement on employees' workplace environment instead. In the process of collective negotiation implementation, thus, emphasis should be laid on improving on both the employees' wage effect and the non-wage effect of workplace environment, instead of sticking to mere formality of focusing on "the quantity" rather than "the quality" of contracts.
