afforestation households earned positive financial returns from forest plantations with seven-year rotations than did not receive support household groups Furthermore, the statistical analysis revealed that afforestation households with more member family, large land size, secure on land rights, off-farm work, ability access to credit have probability participate on forest plantation development policies than other household groups Results from PSM analysis also indicated that forest plantations development policies have a positive impact on the afforestation household welfare through increasing their living expenditure, income, assets value and forest plantation income These findings provide important empirical evidences of the policy factors and special is the III The impact of forest plantation development policies on afforestation households in BacKan province, Vietnam mechanisms may be help through minimizing the factors that hinder afforestation household access to land and finance resources, improve capacity participation in non-farm activities as well as help households participate more in agricultural extension activities On the other hand, this study also help aware the importance of forest plantation development policies when its not only aim significant economic but also ecological and environmental benefits for sustainable development of rural area of Bac Kan province in particular and Vietnam in general Keywords: Policy ， forest plantation policy ， Forest plantation ， impacts ， afforestation households IV TABLE OF CONTENTS 目录 摘要 I ABSTRACT III 引言 1.1.研究背景 1.2.研究目的与意义 1.2.1.研究目的 1.2.2.研究意义 1.3.研究问题与假设 1.3.1.研究问题 1.3.2.研究假设 1.4.研究方法 1.4.1.研究区域选择与概况 1.4.2.研究方法 10 1.5.研究思路 22 1.6.研究内容 24 1.7.研究价值与创新点 26 1.7.1.研究价值 26 1.7.2 研究创新点 26 文献综述与理论基础 28 2.1.概念界定 28 2.1.1 人工林与家庭收入的关系 28 2.1.2.人工林的定义 30 2.1.3.人工林发展的定义 31 2.1.4.森林政策的定义 31 2.1.5.森林政策的重要性 32 2.1.6.人工林发展政策与家庭福利的关系 32 2.1.7 影响的定义 33 2.1.8.评估政策影响的重要性 33 2.2.文献综述 34 2.2.1.评估政策影响的研究 34 2.2.2.人工林建设的研究 39 2.2.3.长期成本收益分析的研究 44 2.3.理论分析框架 48 2.4.本章小结 51 越南的人工林与林业政策情况 52 3.1 越南人工林与林业政策概况 52 3.1.1.人工林特征概况 52 3.1.2.林业政策概况 62 V The impact of forest plantation development policies on afforestation households in BacKan province, Vietnam 3.2.北干省人工林与林业政策概况 78 3.2.1.北干省经济社会特征概况 .78 3.2.2.北干省林业政策概况 83 3.2.3.人工林发展政策对北干省人工林发展的影响 .86 3.3.本章小结 93 人工林发展政策对农户人工林种植的影响 94 4.1.引言 94 4.2.材料与方法 96 4.2.1.文献综述 96 4.2.2.理论框架 97 4.2.3.方法 98 4.3.结果与讨论 101 4.3.1.描述性统计 101 4.3.2.农户对人工林种植的观点 102 4.3.3.农户人工林种植的影响因素 105 4.3.4.人工林发展政策对农户人工林种植的影响 108 4.4.本章小结 114 人工林发展政策对人工林经济效益的影响 116 5.1.引言 116 5.2.材料与方法 117 5.2.1.数据收集 117 5.2.2.数据分析 118 5.3.研究结果分析 121 5.3.1.研究区的生长能力与林地特征 121 5.3.2.人工林种植的成本与收益分析 125 5.3.3.人工林经营活动的经济结果分析 133 5.3.4.敏感性分析 137 5.4.人工林发展政策对人工林的影响 139 5.4.1.人工林种植的经济动机 139 5.4.2.政策性成本项目对造林户的影响 140 5.4.3.政策性收益项目对造林户的影响 142 5.4.4.政策对造林户的综合影响 142 5.4.5.越南人工林种植的前景 143 5.5.本章小结 144 人工林发展政策对造林户的影响 146 6.1.引言 146 6.2.材料与方法 148 6.2.1.样本与数据收集 148 6.2.2 收入的界定与核算 149 6.2.3.理论与实证分析框架 151 VI Appendixes [4] Increase investment for afforestation [5] Villagers are allowed to plant short-term crops in the planted area [6] Others D THE ROLE OF ORGANIZATIONS 10 What support has your family received from forestry extension and research organizations?
