Abstract：The objective of this paper is to analyze and evaluate the current development status and make a prediction of further development for regional logistics in Beibu Gulf of Guangxi Zhuang Autonomous Region.A complex model is established by combining data envelopment analysis and system dynamics ( SD) , with the regional logistics supply and demand index system in focus .The slack variables are essen-tial to the experiment for the change of DEA input factors , which shows that the ideal efficiency value might not be achieved in the real process .However , the proportion of input index can be adjusted to ac-commodate the valid target .Besides , the rate of logistic supply and demand is introduced to demonstrate the ideal development .The rate is produced by simulated value in the model SD , which can be deemed as a benchmark for logistic development of Beibu Gulf in the future .
