The booming platform economy has created a large number of jobs，but labor relations are also facing new problems and challenges. Through a questionnaire survey of platform economy practitioners in Guangzhou，we find that most of them are male in rural areas. Their education level is not low，but their professional skills are generally not high. Most of them do part-time jobs，and increasing their income is the main reason for them to choose the platform for employment. There are many problems，such as low rate of signing labor contract，long working hours，lack of protection of labor standard，high occupational risks（such as accident and personal safety，absence of social insurance and other prominent protection of labor rights and interests）. Platform economy practitioners not only agree with the employment dividend brought by technological progress，but also worry about technical unemployment. In this paper，it is suggested to strengthen the publicity and supervision，accurately identify the types of labor relations，improve employment services，strengthen the construction of labor unions and other dimensions to do a good job in the protection of platform economy practitioners.
