This study analyzes the effects of the Natural Forest Protection Program (NFPP) on the restoration of forest resources in the northeastern forest region of China,an important region because of its ecological and geographical location and timber supply in China,by using panel data sets of 35 forest farms of state-owned forest enterprises.Panel data analysis results show that related policies under the NFPP have had positive effects on forest resources.Planting activity had a statistically significant effect on forest growth and could be reinforced continually by planting tree species suitable for a warming climate in temperate forests.Forest management and protection played a powerful role in increasing the growing stock of the forests.In NFPP areas timber harvests,after implementation of the NFPP,were a positive factor in increasing forest resources if the harvests combined effective tending and thinning under a carefully guided management plan.
