摘要：Korean pig farms face challenges from free trade environment. Many farms have adopted Information System to improve the productivity on the farm. This study applies statistical analysis to verify the productivity gain and its determinants by using information system on the pig farm. Using the farm level weekly data from the PigPlan from 2006 to 2012, we find productivity gain on the farm increases gradually after adoption of the IS on the farm. We also find time of IS usage, the size of farm, farrowing rate, and total piglet per litter link to the productivity gains.
