基于2016年7月~8月在云南省4个国家公园的432份农户调查问卷,运用双重差分模型,研究了国家公园生态旅游发展前后,参与国家公园生态旅游发展的农户和未参与国家公园生态旅游发展的农户在收入方面发生变化的差异。从基本回归结果看,国家公园生态旅游发展前后,处理组和对照组相比较,人均总收入和人均工资性收入均得到了显著的提高;人均财产性收入虽然随着时间的变化而增加,但是与是否参与生态旅游发展无关;参与国家公园生态旅游发展对农户的人均经营性收入、人均转移性收入没有显著性影响。在增加了控制变量后,结果显示,农户的读书时间、家庭耕地面积、林地面积、参与生态旅游发展时间正向影响农户的人均总收入,家庭人口数对农户人均总收入有负向影响;家庭人口数、耕地面积和参与时间对人均财产性收入有正向影响;参与时间会正向影响人均工资性收入,家庭人口数对人均工资性收入有负面影响。
Based on the questionnaire survey of 432 farmers in 4 national parks in Yunnan Province from July to August in 2016, using double difference model, the paper studies the farmers participating in the development of ecotourism in national parks before and after the development of ecotourism in national parks, Differences in the income changes of tourism development farmers. From the results of the basic regression, before and after the development of ecotourism in national parks, the per capita total income and per capita wage income have both been significantly increased compared with those in the control group. Although per capita property income has increased over time, It has nothing to do with whether or not to participate in the development of ecotourism. Participation in the development of ecotourism in national parks has no significant effect on the per capita operating income and the per capita transfer income of farmers. After increasing the control variables, the results showed that farmers’ reading time, family cultivated land area, woodland area and the time of participating in eco-tourism positively affected the total per capita income of farmers and the number of households had a negative impact on the total per capita income of farmers. The population, cultivated land area and participation time have a positive impact on the per capita property income. The participation time will positively affect the per capita wage income, and the household population will have a negative impact on per capita wage income.
