A research on relations between governance modes and efficiency in China's urban bus transport service

With a case of China's urban bus service, this paper combines the methods of data envelopment analysis with Tobit regression to analyze the efficiency differences between market-oriented mode and government-oriented mode. It shows that the mean of market-oriented mode efficiency is higher than the mean of government-oriented mode efficiency, but both of them are low. Furthermore, it shows governance mode actually affect efficiency. Specifically, the increasing market competition and enterprise scale indeed improve the efficiency. While enterprise scale has an inverted U shape relationship with the efficiency.
