摘要： Based on survey data from 832 maize growers of four major maize production regions in China, on-farm maize losses were assessed and the effects of Internet access to agricultural information on the losses were evaluated. The results showed that on average 4.5%, 4.0% and 3.7% of maize was lost in the harvest, drying and storage stages, respectively. This indicated that at the farm level, 19 Mt of maize is lost annually in China, and these losses have considerable economic, resource and environmental impacts. Additionally, Internet-based access to agricultural information was found to be positively related to reduced maize losses. Compared with farmers who do not access agricultural information from the Internet, farmers with Internet-based access to agricultural information experienced 3.2%, 1.5% and 3.6% lower losses in the maize harvest, drying, and storage stages, respectively. Therefore, enhancing farmers access to agricultural information could increase the maize supply by 7.89 Mt and enhance the utilization of 1.02 Mha of farmland. Additionally, 0.39 Mt of fertilizer could be saved, and the carbon emission and water usage could be reduced. It is recommended that the government accelerate the removal of barriers to farmers using the Internet to access agricultural information.
