基于数理模型的二手房买卖经纪模式仿真比较

Simulated comparisons of resale housing sales brokerage patterns

为研究二手房买卖经纪模式对买方效用的影响,比较不同经纪模式下的买方效用,基于对现实二手房买卖过程及特点的分析,分别构建"单一经纪人"和"双经纪人"模式下的买方效用数理模型并进行求解,最后采用Matlab工具对这2种经纪模式下的买方效用及相关指标进行仿真比较。研究结果表明:1)与"双经纪人"模式相比,"单一经纪人"模式下的买方佣金激励程度小,但经纪人搜寻努力高且买方效用大;2)在其他条件不变的情况下,从买方效用的角度分析,二手房买卖过程中的买方应选择"单一经纪人"模式,以达到促进交易进程的目标。

The effects of resale housing sales brokerage patterns on buyer＇s utility were investigated by the buyer＇s utility for different brokerage patterns.Actual resale housing trading processes were used to develop mathematical models of the buyer＇s utility for＂single broker＂and＂double broker＂patterns.Matlab was then used to simulate the buyer＇s utility and related indexes.The findings show that the ＂single broker＂pattern has smaller buyer to broker incentives than the＂double broker＂pattern,but the broker＇s search efforts and buyer＇s utility are bigger. From buyer＇s utility perspective,the buyer should select the ＂single broker＂pattern to promote the resale housing trading process when all other variables are unchanged.
