Abstract: Forestry is the foundation for building an ecological safety barrier in Beijing and consolidating green development. The high-quality development of the forestry industry is an urgent requirement for responding to the new situation and new goals, building ecological civilization, and implementing the strategy of rural revitalization. Based on the development status of the forestry industry in Beijing and 391 questionnaire data, the research uses structural equation models to analyze the impact of government support, technological innovation, industrial agglomeration, economic momentum, and resource endowment on the high-quality development of the forestry industry. Besides, the models also explore the mediating effects of economic momentum and resource endowment. The results show that: first, government support does not have a significantly direct positive effect on the high-quality development of the forestry industry, while technological innovation, industrial agglomeration, economic momentum, and resource endowment all contribute to the direct promotion of the high-quality development of the forestry industry, and the promotion of technological innovation is the most significant.Secondly, government support, technological innovation, and industrial agglomeration can indirectly drive the high-quality development of the forestry industry through economic momentum and resource endowments.
