Abstract

Since reform and opening policy，with the transformation of our social and economic system，the constant adjustment and upgrading of industrial structure，the pace of urbanization accelerated，to emerged a large number of urban laid-off workers and surplus rural labor force，due to flexible employment mechanism，the low demand of employment for informal employment，to meet employment needs for a variety of different hierarchy’s labors，so it becomes an important channel of surplus labor forces and the new labor forces and it has had a major impact on the labor market，the labor market has led to a significant change—Informal employment has become the mainstream of urban employment population. The group has neither a special labor skills nor more social capital available，simply rely on selling their labor to employment，they are a typical social vulnerable groups. Their employments are vulnerable to discrimination；Labor remuneration can not guaranteed；Labor health and safety conditions are bad，work is dangerous，prone to accidents；High labor intensity，lack of respect for human dignity；Poor living conditions，lives are guaranteed，Their mental health is not guaranteed；A lot of them have low education，fewer opportunities to receive education，labor rights can not be guaranteed. Especially in some private private enterprises，work environment are very bad，frequent accidents，the groups often become victims of security incidents；Indefinitely extend their working time，Health seriously is damaged，Phenomenon is growing about malicious deduction and arrearing payment，game abilities of the groups’ labor relations are very low，rights are infringed，these seriously affected and threatened to building of harmonious labor relations in China and the equitable sharing of social development outcomes，and it has become a serious hidden danger to the social stability.

The International Labour Organization put forward the concept of “decent work” for the social harmonious and stable development，to solve all kinds of problems of social and labor aspects under the conditions of the globalization，and took it as a strategic goal to solve all the social and labor problems. Chinese government actively respond and support the realization of decent work and regarded it as a way to development of harmonious labor relations and building a harmonious socialist society，But in our country urban informal employment groups’ labor rights protection status is far from the requirement of decent work，to achieve the government's goal of decent work for all the people，must be in order to promote decent employment of informal employment groups and to protect the legitimate labor rights of informal employment groups.

The cornerstone of a harmonious society is the harmonious labor relations，but the core of the harmonious labor relations is protection of labor rights and achievement of decent work，Based on this，this study regards six modern western labor relations theories as the main line，formed the theoretical basis of this study through combining the institutional attachment theory of system and social equality together；Through defining the connotation of decent work and labor rights and characteristics，to clarify the relationship between decent work and labor rights；After determining the theory foundation of the study，sort out historical development process of Chinese urban informal employment labor rights protection through the historical research in this study，using the method of qualitative analysis to summarize the present situation of Chinese urban informal employment groups’ labor rights protection，and the using quantitative analysis method to analyse macro historical data of high degree of confidence to find out our current urban informal employment groups’ labor rights protect problems，using normative analysis method to deal with these problems and explore its causes；On the basis of these，the study explored effects factors and outcome variables of urban informal employment groups’ labor rights protection，formed eight related assumptions，and constructed the theoretical model of this study；selected theoretical measure index system of urban informal employment group labor rights protection through decent work concept and connotation，formed finally surveys Scale of the urban informal employment groups’ protection of labor rights through membership，relevance，project analysis，reliability and validity of empirical research methods；Proposed eight hypotheses of theory，proved the validity of the theoretical model；This study foud out through theoretical and empirical analysis that：because of labor market imperfections，urban informal employment has become the mainstream of the current employment，led labor market order more complicated and confusing，Strong capital and weak labors’ phenomenon can not be effectively controlled，Our labor law and labor regulations and polices are not perfect，Labor supervision is not in place，leading to some private private enterprises made use of loopholes in the law to infringe the legitimate labor rights；In some private enterprises，No trade union organization or union organization is not perfect，not independent，led trade union organization can not truly represent the legitimate interests of workers；Urban informal employment groups have their own low quality and working skills level，weak legal awareness of rights and other issues. In view of these，this study proposed to build a multilateral cooperation complementary new model of labor rights protection of government，business organizations，trade unions and urban informal employment groups themselves，through this ultilateral mutual restricting powers，to construct a relatively strong and complementary cooperative system.

In this study，the structure is composed of eight chapters，the specific structure is as follows：

Chapter 1 Introduction.This chapter focuses on the background of topics，the main research content and method，research ideas，research status at home and abroad，interpreted and introduced the structure arrangement and innovation.

Chapter 2 The theoretical basis of the informal employment and related research. this study regards six modern western labor relations theories as the main line，formed the theoretical basis of this study through combining the institutional attachment theory of system and social equality together，research on the informal employment at home and abroad are reviewed，defined the connotation of informal employment. On this basis，this chapter also used the theory of social stratification to divide the urban informal employment groups into two groups of benefited and compromised interests，thus locking the main object of study in this study，compromised interests’ the urban informal employment groups.

Chapter 3 Studies about the labor rights and decent work. This chapter analyzed and discussed the relevant research at home and abroad about labor rights and interests，on this basis，the connotation of labor interests were defined；Labor rights were divided into five levels according to Maslow's hierarchy of needs：right to life，right to security，the right to social recognition，respect for rights and the right to self-realization，to pave the way for the theoretical model of the following；This chapter also reviewed research about decent work abroad，proposed suitable connotation and characteristics of decent work for China，based on this，analysed and discuced the relationship between labor rights protection and decent work’s achievement.

Chapter 4 Historical evolution and existing problems about the Informal employment groups’ labor rights protection. This chapter mainly used the method of historical analysis to divided urban informal employment group labor rights protection into four historical stages，studied these four stages to the historical evolution，Each stage discussed separately three aspects such as social security，labor protection and staff development，the using quantitative analysis method to analyse macro historical data of high degree of confidence to find out our current urban informal employment groups’ labor rights protect problems，using normative analysis method to deal with these problems and explore its causes.

Chapter 5 Construction research hypothesis and theoretical model of the informal employment groups’ labor rights protection from the perspective of decent work. This chapter first discussed the influencing factors of the urban informal employment labor rights protection：labors’ individual property，organizational ownership property，regional economic attribute and trade unions，these factors have influence on the labor rights protection；Secondly discussedaftereffect variables about urban informal employment groups’ labor rights protection：Labor rights protection affected on labors’ quality of working life，organizational performance and harmonious labor relations’s construction；Finally Proposed eight theoretical assumptions，on the base of eight theories assumptions，constructed a theory model of urban informal employment group labor rights protection.
