摘要
在信息爆炸的时代,信息的有效供给才是使农民跨越"数字鸿沟"享受"信息红利"的关键。本文对基于手机短信的农业信息服务与农民的销售价格之间的因果关系以及内在的作用机制进行了实证分析。研究结果表明,信息的有效供给确实能够显著提高易腐农产品的销售价格,但这种因果关系仅限于易腐农产品(豆角)。本文认为未来我国农业信息化建设的关键在于提供准确及时有效的市场信息,提高农民的信息获取能力,缩小"二级数字鸿沟"。
The effective supply of information is the key factor to help farmers get rid of digital divided and enjoy digital provided. This paper discusses the impact of SMS-hased Agri- cultural Information on farm-gate price of farmers, and analyzes the internal mechanism. In order to reduce endogeneity, we apply propensity score matching. The results prove that the use of SMS-based agricultural information does have statistically significant effect on farm- gate price. But the impact is only effective for perishable products （cowpea）. In the future, the timely, accurate and effective information provided will be the key factor for the agricul- tural informatization construction in China.
