中文摘要：

以福建省沙县、顺昌县为例，采用林权改革后的2007～2009年面板数据，运用DEA—Mlamquist和Tobit两阶段分析法以及单因素方差分析检验，测算了南方集体林区家庭林地经营效率，分析其影响因素。发现林权改革后家庭经营的林地规模与全要素生产率之间可能存在倒U型关系，而非简单正向或负向关系；林业投资、农户兼业程度、户主年龄对生产效率影响显著，其余变量不显著；家庭林地经营规模偏小，流动性不足；林地经营效率分化明显等问题。

英文摘要：

This paper took the collective forestland in the counties of Sha and Shunchang of Fujian province as an example and applied DEA-Mlamquist, Tobit two-step method as well as single factor variance analysis on the panel data from 2007 ~ 2009 after the forest tenure reform to examine the household forestland operating efficiency and further its influencing factors in the Southern Collective Forest Area. The results suggested that there is an inverse U shape curve relationship between the forestland operating scale and total factor productivity after the forest tenure reform rather than an simple positive or negative relationship as previously assumed. Factors such as forestry investment, level of rural household diversification and age of householder significantly influence the productivity efficiency while the rest have less significance. We also found out that forestland operation fall short in oeration scale and forestland liquidity. It also has sever problem of efficiency differentiation.
