基于DEA和FCA对房地产业投资有效性的研究

Research on the Effectiveness of Real Estate Investment Based on DEA and FCA

摘要:

房地产行业具有多输入和多输出，以及主观因素影响较大的特点，DEA和FCA的结合较适用于此类典型的复杂系统。在综合评价体系中，对于可以量化的指标，利用数据包络分析方法评价各DMU的相对有效性，利用隶属度函数模糊化相对效率，与其他非量化指标一起进行模糊综合评价。这对于兼有主客观指标的综合系统提供了新的系统评价的方法和思路。本文以全国八个省为例，对房地产投资有效性进行评价。

Abstract: The real estate industry has multiple inputs and outputs characteristics and is influenced by subjective factors greatly. The combination of DEA and FCA is applied to this typical complex system. In the comprehensive evaluation system, for quantifiable indicators, the relative efficiency of every DMU is calculated based on DEA and then fuzzified by membership functions. The result of DEA is of great objectivity, making FCA more convincing instead of expert scores. It provides a new method to evaluate comprehensive systems. This is a case study to research the effectiveness of real estate investment in 8 Provinces of China.
