摘要
为了检验"农业保险需求影响因素"的现有实证结果是否受到了具体研究特征的影响,本文选取国内现有研究农业保险需求影响因素的47篇主要实证文献,利用Probit和Logit模型,对文献的实证研究结果进行了荟萃分析。回归结果表明,"农业保险需求影响因素"在实证研究中的研究结果受具体研究特征的影响,主要包括"自变量个数""研究年份""是否考虑政府补贴""样本数量"等。因此,建议研究人员要注重这些研究特征对研究结果的影响,做好抽样设计,尽量在调查问卷环节从样本容量、样本分布等方面控制这些特征的影响,避免产生不必要的研究投入,并在得到结果后谨慎提出政策建议。
In order to test whether the existing empirical results of 'influencing factors of agricultural insurance demand'are affected by specific research characteristics,this paper selects47 main empirical documents of domestic research on the influencing factors of agricultural insurance demand,uses Probit and Logit models to conduct a meta-analysis on the empirical findings of these documents. The regression results show that the results of 'influencing factors of agricultural insurance demand'in different empirical research are influenced by specific research characteristics,including 'number of independent variables', 'year of study', 'whether government subsidies are used as independent variable','sample volume ' etc. Hence,we suggest that researchers should take these results into account and design sampling properly,with a discreet control on sample volume and distribution,so as to avoid unnecessary waste of scientific resources. We also emphasize a prudent application of these results.
