Abstract Based on the investigation of 160 different under-forestry economic management entities in Guangdong Province，the economic production efficiency of different production types and different management agents were measured by using the CCR method of DEA model，and the Tobit model was constructed to analyze the influencing factors of the under-forestry economic production efficiency．The results are as follows：（1） From the perspective of the three production types，the technical efficiency and scale efficiency of aquaculture are the highest，followed by planting and breeding，while that of planting are the lowest．（2） From the perspective of the three management entities，the corporate- led farmers show the highest technical efficiency and scale efficiency，and the highest comprehensive efficiency，while the lowest technical efficiency is the single-management farmers，and the cooperatives led farmers have the lowest scale efficiency．（3） Among the factors affecting the economic productivity of the under-forest economy，economic profit，irrigation conditions，education level of the household head， social position of the household head， technical training and joining economic organizations all have positive impacts on the improvement of the economic productivity of the under-forest economy，while age has a negative impact．Therefore，the government needs to provide policy support in technical training， financial subsidies，the cultivation of new business entities，social service institutions，and attracting outstanding farmers to return to their hometowns to engage in green and efficient understory economic production or entrepreneurship.
