本研究首先對鹿谷鄉內台灣大學實驗林的契約林農進行問卷調查，再以調查資料利用二元邏輯迴歸法分析決定契約林地經營集約與否的因素。實證結果顯示，有利於契約林地集約經營的因素為：易到達林地、非高齡林農、曾申請撫育補助以及營林收入佔所得比例高。換言之，可減少支出和增加收入或提高相對收入為決定林地集約經營與否的重要因素。然而，林地契約的類型及取得方式的不同並未在集約經營上造成差異。

This study first conducted a questionnaire survey to investigate the users of the lease forestlands of National Taiwan University Experimental Forest in Lugu Township. The survey data was then analyzed by binary logistical regression for determining the factors of intensive use of lease forestland. The results showed that the conducive factors to intensive use of lease forestland were:
easier access to forestlands, non-elderly forestland users, having applied for silvicultural subsidy, and higher proportion of forest revenue to household income. In other words, factors able to reduce cost
or to increase revenue and to raise the relative income from forestland were important to deter-mine whether or not intensive use of lease forestland. However, various types and origins of lease contracts did not make difference in the intensity of forestland use.
