摘　　要：新一轮集体林产权改革是否会导致农户过量采伐林木从而抑制森林资源的可持续增长一直存在争论。以改革所形成的产权强度为切入点分析认为,改革使得集体商品林的产权强度高于集体公益林。基于云南省2005年和2015年的森林资源调查数据和农户调查数据,以森林资源的郁闭度和蓄积量作为森林资源增长的数量和质量指标,以分林到户的集体公益林作为对照控制组,以分林到户的集体商品林作为实验组,采用DID模型实证检验产权强度差异对森林资源增长的影响,结果表明:配套改革提高了农户持有的商品林地的产权强度,产权强度的提升又通过激励农户的经营行为,提高了林地的郁闭度和蓄积量,促进了森林资源增长;农户持有的集体商品林没有出现过量采伐。There are always many controversies about whether the new round of collective forest property right reform will lead to farmers'excessive deforestation so as to inhibit the sustainable growth of forest resources.Taking the property right intensity as the breakthrough point,this paper shows that as a result of reform,the property right intensity of collective commercial forest is higher than that of collective public welfare forest.Based on the forest resources survey data and farmers'survey data of Yunnan Province in 2005 and 2015,with the canopy density and stock volume taken as the quantitative and quality indicators of forest resources growth,farmers'collective public welfare forest taken as the control group and farmers'collective commercial forest taken as the experimental group,the impact of property right intensity on forest resources growth has been test by adopting the DID model.The results showed that the reform has improved the property right intensity of farmer-owned collective commercial forest;the increase of the property right intensity has further raised the canopy density and stock volume and promoted the growth of forest resources through stimulating farmers.There was no excessive deforestation on collective commercial forest land.
