摘要

>Super-efficiency DEA-CCR/BCC and Windows analysis models are firstly used to analyse the productive efficiencies of Chinese toll highway enterprises listed on the Shanghai and Shenzhen stock markets during 2004 and 2013. Through cross-sectional data and panel data analysis, the research indicated that (a) the large-scale toll highway enterprises have no significant advantage of productive efficiency over the middle and small-scale toll highway enterprises; (b) Chinese toll highway enterprises show decreasing returns to scale except for several enterprises which have scale efficiency at present; (c) the productive efficiencies productivity shows large annual differences; (d) there is great effect on productive efficiencies whether toll highway enterprises could reduce the cost of production to a certain extent; (e) the productive efficiencies of Chinese toll highways are low as a whole; (f) with increasing age of enterprise established, the productive efficiencies of Chinese toll highway enterprises show volatility and slowly rising overall trend.
