With the rapid development of the platform economy，the gig economy and the sharing economy，the scale of employees in the new employment patterns represented by delivery personnel and car-hailing drivers keeps expanding. Aimed to protect their legitimate rights and interests，some progress has been made in expanding the coverage of social insurance. However，current policies cannot effectively cope with the different labor relation and flexible manner of working due to the difficulties in identifying labor relations，the negligence of authority and low attractiveness of social insurance. To solve these problems，this study provides insight into the current situation through field research，symposium and questionnaire survey. All suggestions are of great reference value such as improving social insurance policies，launching pilot projects of occupational injury protection，raising workers motivations in insurance，etc.
