Improved data envelopment analysis model based on geometric mean model
According to the characteristics of the circular economy conception of the under-development regions under new economy situation, the improved data envelopment analysis model based on geometric mean model is reconstructed in the paper through increasing unexpected input (waste recycling quantity) in the input and increasing unexpected output (waste discharge quantity) in the output; then, the improved data envelopment analysis model is adopted to evaluate the efficiency of the circular economy of the under-development regions in 31 provinces and cities in China during 2002-2012. The research result shows that the efficiency of the circular economy of the under-development regions in China is generally improved, and the scale efficiency gradually tends to reach the optimum efficiency, but the obvious insufficiency of pure technical efficiency has influenced the development level of the circular economy of the under-development regions in China.
