Abstract: This paper introduces the concept and model of bullwhip effect into the operation of virtual enterprises based on the supply chain management.We uses the varied coefficient ARIMA model to forecast the demand information of upstream and downstream firms in virtual enterprises,and studies the discrepancy of the order level between the upstream and downstream firms,then prove the existence of the bullwhip effect in virtual enterprises.At last we conclude that non-stable demand is also the important factor besides agile management and information sharing,which influence the bullwhip effect,and discuss the condition that bullwhip effect emerges under the situation of complete information sharing.

Key words: virtual enterprise, bullwhip effect, ARIMA model, non-stable demand
