文章从公共管理视角,运用传统的公共产品需求和供给理论阐述了林木良种生产的公益性特征,解释了林木良种的公共产品属性。指出,需求主体对林木良种的选择愿意低,不发达的林业产业对林木良种的需求弹性低,公益性林木良种使用激励不足等,是供需调节市场失灵的主要原因。 From the perspective of public management, the article expounds the public welfare characteristics of improved varieties of forest trees by using the traditional theory of public goods demand and supply, and explains the public goods attributes of forest good varieties. It is pointed out that the main body of the supply and demand adjustment market failure is the main reason that the main body of the demand is willing to choose the good forest species and the underdeveloped forestry industry has low demand elasticity to the forest good species and insufficient encouragement to the public welfare forest species.
