Forest resources are abundant in the south of China,and forestry is an important source of income for farmers in the collective forest region.As the main manager in the collective forest area,the farmers' management investment behavior plays an important role in the development of forestry.There are many influencing factors that affect the behavior of forestry production input.However,as one of the influencing factors,the forestland circulation period has an important influence on the investment of forestry production.To stabilize the forest land circulation,improve the level of intensive management of woodland resource in Zhejiang province to provide reference for forestry development and farmers' income,this article,based on the sample survey data in Zhejiang province and using multiple linear regression,analyses the influence of the forest land transfer period on the bamboo forest production inputs.The research results show that the influence of the transfer period on bamboo forest production input presents an inverted U type.When the transfer period is 38 years,the farmers production input of bamboo forest is the biggest.
