摘　　要：以福建、江西、湖南、四川、浙江、广西、河南、山东、辽宁9个省(区)18个县(市、区)2 420户农户调查数据为基础,定量分析了集体林分权条件下林地细碎化程度、农户投入水平及其林地林产品产出水平之间的关系,以验证集体林权制度改革后林地细碎化经营的经济合理性。实证分析结果表明:以S指数衡量,中国集体林地细碎化程度达到0.41。相关性分析表明,在一定的区间内,农户林地细碎化程度越大,越不利于其林业投入;当农户林地细碎化程度低于0.22或高于0.51时,农户投资林地的积极性则呈现相反的变化趋势。投入产出模型估计结果表明,由林地块数所反映的农户林地细碎化程度对其林地林产品产出构成负向影响,其他因素(劳动投入、物质投入、林地面积)对林地林产品产出均有正向影响。以竹材为目标林产品,农户林地细碎化程度对其产出并没有构成负向影响,林地面积对其产出有负向影响,而劳动投入的正向影响最大。Based on data collected from a survey of 2 420 households in 18 counties （ cities, districts） in the 9 provinces （regions） of Fujian, Jiangxi, Hunan, Sichuan, Zhejiang, Guangxi, Henan, Shandong, and Liaon ing, this paper analyzed quantitatively the degree of woodland fragmentation, farmers＇ input and relationship between output and input under the conditions of the decentralization of the collective forestry property in order to verify economic rationality of fragmentation woodland operation after the reform of collective forest right sys tem.The empirical results showed that the degree of China＇ s collective forest fragmentation reached 0.41 withthe index S measuring. Correlation analysis results showed that the greater the degree of farmers＇ woodland frag mentation, the more detrimental to their investment in forestry within a certain range.When the degree of farm ers＇ woodland fragmentation was lower than 0.22 or higher than 0.51, farmers＇ enthusiasm about investing in woodland was of the opposite trend.The estimating results by the input-output model showed that the degree of farmers＇ woodland fragmentation by the number of woodland blocks had a negative impact on the products out put of the woodland while other factors like labor input, material input, and wooded area had positive effect. Taking bamboo products for example, the degree of farmers＇ woodland fragmentation did not constitute a nega tive impact on its output, but the forest area had a negative impact on its output, and labor input had the most oositive effect.
