The Internet Plus action plan (IPAP) plays a significant role in promoting China’s industry upgrades and high-quality development of the economy. As IPAP is evolving into a new phase of in-depth development, related technologies are constantly being upgraded and a variety of industrial integration models emerges. Therefore, it is urgent to systematically investigate recent policies and plans related to IPAP, to analyze its current situation and identify problems, then to further optimize relevant policy systems. In this work, recent policies and plans released to promote IPAP are systematically reviewed, including national and local ones. Based on review and surveys, the current problems of IPAP policy system are discussed, including fragmentation of policy documents, homogenization of local policy documents, inadequate supporting measures, and lacking of phased evaluation methods. Moreover, policy recommendations are proposed to promote IPAP’s further development. Recommendations include measures to: (1) establish and improve a systematic policy formulation mechanism for IPAP, (2) improve the coordination system to promote IPAP, (3) reasonably strengthen the financial support for IPAP, and (4) improve related laws, regulations, and standards on IPAP. It is expected that this work can provide a reference for relevant research on IPAP policy systems.
