当前林业高质量发展已经成为新时代的必然要求,林下经济产业成为当代林业发展的重要形式,具有广阔的发展前景。本研究从林下经济政策文本出发,基于LDA主题模型和政策文本量化的研究范式,识别林下经济相关政策主题,并使用Nvivo内容分析法进行主题验证。从识别到的7个政策主题中,对林下经济产业政策进行了深入剖析,并从政策研究与管理的角度,提出了若干政策建议,以期提高林下经济政策实效性,推动林下经济高质量发展。

The current high-quality development of forestry has become the inevitable requirement of the new era,and the under-forest economy industry has become an important form of contemporary forestry development with a broad development prospect.In this paper,starting from the under-forest economy policy text,based on the research paradigm of LDA theme model and policy text quantification,we identify the policy themes related to the under-forest economy and use the Nvivo content analysis method for theme validation.From the seven policy themes identified,the industrial policies of the under-forest economy are analyzed in depth,and a number of policy recommendations are put forward from the perspectives of policy research and management,with a view to improving the effectiveness of the under-forest economy policies and promoting the high-quality development of the under-forest economy.
