摘要 地形和区位条件差异是导致农户林地投入和产出水平呈现区域差异性特征的重要因素。利用全国8省(区)1 790户样本农户数据,采用回归模型,定量分析地形和区位等因素对农户林地投入和林地产出水平的影响,以及这些因素影响下的农户林地投入和林地产出水平之间的关系。结果表明:区位条件中,农村经济发展水平、通达程度和人口聚集度对农户林地投入和产出水平影响显著,对农户林地投入水平的影响系数分别为0.128 8,0.128 7和0.162 9,对林地产出水平的影响系数分别为0.152 4,0.171 8和0.198 9;地形条件中,农户林地产出水平的高低受地形条件影响显著,山区和丘陵林地产出水平明显高于平原地区,山区和丘陵地形对农户林地产出水平影响系数分别为0.101 9和0.016 9;除地形条件和区位条件之外,经营资金的主要来源、林木采伐指标的申请难易程度、是否有产品市场信息服务、是否有融资服务、是否有中介服务等因素对农户林地投入和产出水平也有显著影响。基于上述结果,提出相应的对策建议。 The differences in the terrain and geographic conditions are the important factors resulting in the regional differences in the farmers’input and output of forestland (FIOF). With 1 790 data coming from 8 provinces,by regression models,this paper quantitatively analyzed the impact of the factors on the FIOF,such as the terrain,geographic and other factors. It also analyzed the relations between the FIOF under the influences of these factors. The results showed that: geographically,the rural economic development,the accessibility and the population concentration had significantly affected the FIOF. Topographically,farmer’s income of the forestland was significantly affected by terrain conditions,and farmer’s income of the forestland in the mountains and hills were significantly higher than in the plains. Among them,the affecting coefficients of the rural economic development,the accessibility and the population concentration on farmer ’s investment of forestland were 0. 128 8,0. 128 7 and 0. 162 9. Its affecting coefficients on farmer’s income of forestland were 0. 152 4,0. 171 8 and 0. 198 9. The impacting coefficients of mountainous and hills terrain on farmer’s income of forestland were 0. 101 9 and 0. 016 9. In addition to terrain and geographic conditions,the main source of operating funds, the access to easily apply for timber harvesting indicators,the access to have the product market information services,the access to have financial services,the access to have intermediary services,which had significant impact on the FIOF. Based on these results,the corresponding countermeasures were put forward.
