为了更好地发挥中巴地球资源卫星的社会效益,同时为中巴地球资源卫星的使用和管理部门提供决策参考依据,应用条件价值法(CVM),采用支付意愿问卷调查的方式,通过数据统计和回归分析,对中巴地球资源卫星的社会效益进行定量评价,得到了影响中巴地球资源卫星社会效益支付意愿的主要因素.共发放问卷2330份,收回有效问卷2285份,通过对问卷数据的描述性统计,得到支付意愿的分布情况和在各单一因素影响下的变化规律.用主成分分析简化影响因素,运用二元Logit回归模型和Tobit模型,得到在所有的影响因素中,对中巴地球资源卫星的重视性、个人平均年收入是影响被调查者对中巴地球资源卫星社会效益的支付意愿的主要因素.研究结论使得中巴地球资源卫星的收益和成本的比较成为可能,为政府制定相关政策提供理论基础.
In order to give full play to the social benefits of China Earth Resources Satellite (SAR) satellites, at the same time, provide reference for the use and management of China Earth Resource Satellite (SAR) satellites by using CVM, pay-as-you-go questionnaires and data statistics And regression analysis of the social benefits of China Earth Resources Satellite (SAR) satellite, we got 2330 questionnaires and collected 2285 valid questionnaires, Descriptive statistics, the distribution of willingness to pay and the changing rules under the influence of single factors.Using principal component analysis to simplify the influencing factors, using the binary Logit regression model and Tobit model, we can get the conclusion that among all the influencing factors, The importance of earth resources satellites and the average annual income of individuals are the main factors that affect the willingness of respondents to pay for the social benefits of China Earth resources satellite satellite.The conclusions of the study make it possible to compare the benefits and costs of earth resources satellites between China and Pakistan, Formulate relevant policies to provide the theoretical basis.
