In China, scenic and historic areas are protected areas which are highly integrated with natural and cultural resources. The study analyzed policies based on the theory of policy instruments using quantitative and content analyses. The results demonstrated that China’s scenic and historic areas have experienced four phases of development: primary development (1980–1994), exploration and growth (1995–2006), deepening and maturity (2007–2018), and integration and optimization (2019–2023). Policy intensity is trending upwards, and contemporary policy authority and restraints are insufficient. The policy instruments showed an imbalance, and are mainly environmentally based, with only a few supplies and demand based. Policy topics mainly include management and planning protection. The Chinese government has played a leading role, taking many restraining measures to quickly protect scenic resources. Stronger and more effective policies with more specific content will favor the protection of scenic areas. In the future, financial input, international exchanges, and outsourcing services should be increased to promote the vital development of scenic areas. Legislation, establishment, social participation, operation, and ticket systems must be comprehensive. Overall, the study provides theoretical support for further reforms of China’s scenic areas and lessons for improving the conservation quality of the world’s protected areas.
