This gap in practice, on the one hand, reflects the misunderstand-ing of the right to personal data portability, and on the other hand, is a result of the negative externalities, practical costs and technical lim-itations of the right to personal data portability. Based on rethinking the right to data portability, we can somehow solve practical problems concerning the right to personal data portability through multiple measures such as promoting the fulfillment of this right by legislation, optimizing technology-oriented operations, refining response process mechanisms, and enhancing system interoperability.展开更多

At present, there are still some weak areas in China's construction of a manufacturer of quality, such as backward technologies comparing with world's leading players in some areas, limited contributes to the formulation of international standards, insu cient invests in building a system of supporting policies concerning nance, banking and taxation, and scant attention to cultural development as a manufacturer of quality. China should attach more importance to the technological research and development in these weak areas, align its manufacturing standards system with international standards, improve its system of supporting policies concerning nance, banking and taxation, and make more e orts in the development of advanced manufacturing system.展开更多
