基于NOM-Hybrid DEA和Meta-frontier的效率模型研究

An efficiency analysis based on NOM-Hybrid DEA and Meta-frontier frameworks

利用NOM-Hybrid DEA理论对共同边界(Meta-frontier)框架进行了重建,使得新框架能够处理带负值的径向与非径向的变量问题,从而求得技术差距率(TGR),结果表明新框架模型是有效的.在算例分析中,出现了瑕疵点,给出了一定程度的解释,但是仍然需要进一步研究,尝试将共同边界框架分析(Meta-frontier frameworks analysis)理论进一步扩展,使得该理论能够更加广泛地在实际中应用,并且测量更加精确可靠,进而在经济分析和管理应用中发挥更大作用.

In this paper, we rebuild Meta-frontier framework with the NOM-Hybrid DEA, thus it can handle radial and non-radial variable problem with negative, and we successfully attain the technology gap ratio(TGR). Subsequently, we give a numerical example to interpret the new framework. The results show that the new framework of the model is effective. Although we give a certain degree of interpretation for the emergence of point defects, it still needs further study from a theoretical and empirical point to give a satisfactory answer.In this contribution, we attempt to push the framework of Meta-frontier analysis theory further so that it can be more widely used in practice, furthermore, the calculation is more accurate and reliable, and thus plays a greater role in economic analysis and management applications.
