Abstract:Based on the implementation of the Law on the Progress of Science and Technology in China"s local provinces and cities, starting from the development status and legal environment of new technologies and new applications, this paper makes a comparative analysis of the differences and characteristics in the legislative model, legislative design and legislative content of new technologies and new applications in local science and technology regulations in various provinces and cities. It is found that at present, local laws and regulations generally adopt the mode of promoting legislation to encourage new technologies and applications, but the chapter design is not systematic, the number of articles is small, the position is scattered, and the awareness of problems is weak; Local laws and regulations on new technologies and applications have their own characteristics, but there are some problems such as insufficient promotion incentives and legal responsibility vacuum. Suggestions: All localities should strengthen the legislation on new technologies and new applications as soon as possible, improve the promotion legislation mode, explore the systematic system design of special chapters or special legislation in combination with local conditions, solidify the practical experience of research and development, application, promotion, encouragement and supervision, adjust the supervision system, clarify the illegal results, and promote the self-reliance and self-reliance of high-level science and technology in this region.
