在南方集体林区,非木质林产品资源成为农户增收的主要来源之一,但在农户非木质林产品经营中需要考虑投入要素的有效性以及生产资源如何合理配置问题。论文以临安市山核桃产业和仙居县杨梅产业为例,分别选取两个县(市)共167户林农2009年横截面数据为样本,在农户微观层面运用C-D生产函数,实证分析了投入要素及影响因素在非木质林产品生产中的作用。结果表明,农药化肥投入、地域因素都对两个地区非木质林产品生产有显著影响,而劳动力投入和林业劳动力人均种植面积因素则只对山核桃生产有显著影响。笔者认为需要通过积极推广农户从事非木质林产品的经营,重视农药化肥生产资料投入以及促使劳动力季节性回流等措施促进非木质林产品经营。
The non-timber forest products(NTFP) became the main source of rural households income in southern collective forest area, but it’s necessary to consider the effectiveness of input and resource allocation for NTFP management. This paper took hickory in Lin’an and waxberry in Xianju as cases, and discussed the role of input and causal factors in non-timber forest production using the C-D production function for 167 households samples in 2009 from these two cases with the micro-household perspective. The results show that the factors of both fertilizers and chemicals input and area have influenced significantly the output of NTFP, and input of labors and planting area per capita for forest labors has influenced significantly the output of hickory. There are many important suggestions for improving the NTFP management such as popularizing the NTFP plantation for farmers, paying more attention to the fertilizers and chemicals input, promoting the labors return to local area.
