Business efficiency plays an essential role in the development of high-tech enterprises. This paper uses DART's value-sharing theory to study enterprises from three aspects. Then this paper uses the method of DEA and DART to analyze the business performance of high-tech enterprises in 30 provinces and cities. Research indicates that the overall management efficiency of the Chinese high-tech industry is poor. There is no apparent positive correlation between the business efficiency of each sector and the local economic situation. Finally, the paper gives some countermeasures according to the conclusion of the evaluation.
