Evaluation on overall relative efficiency of China traffic and transportation system based on data envelopment analysis

This paper evaluates the relative efficiency of decade's development of China traffic and transportation system and present regional development based on data envelopment analysis. The result and analysis conclude that the input and output efficiency of China has not promoted significantly, and the unbalance development between regions exists. Some regions have a relatively low efficiency and little correlation with their developing levels, so great attention should be paid to promote the efficiency of regional traffic and transportation productivity.
