Abstract: Irregular economy is one important phenomenon in our country, which is playing a more and more important role in our society, thus it can not be treated as transparent or suppressed. Employees in the irregular economy can be hardly protected under the existing formal security system. While the general trend in the world is that irregular social security system is getting weaker and weaker, therefore a rational selection to solve the problem is to reform the existing formal social security system to make it function in irregular employees. A practicable reform approach is to pull in social endowment pension system, which avoids the barriers of irregularity. The social endowment pension system provides irregular employees a dependable forecast, thus changing their behaviors and strengthening their ability of coping with risks, consequently improving their working efficiency and relieving poverty.
