Benchmarking with nonconvex production possibility set through data envelopment analysis: An application to China’s transportation system
作者：
Highlights：
• Benchmarking with nonconvex production possibility set (PPS) is emphasized.
• Correlation between nonconvex PPS and convex PPS is presented.
• The closest benchmark with least effort is obtained with nonconvex PPS.
• A new efficiency measure is introduced and a benchmark index is conceptualized.
• An empirical application to China’s transportation system is investigated.
