摘要：AbstractThe aim of this study is to explore how the household spends the money for transportation as well as how life stages and related household attributes contributed to transportation fee expenditures in Jakarta Metropolitan Area. The substantial characteristics of household attributes among life stage categories are taken into consideration. The analysis was performed using Stochastic Frontier Model, and the concept of production frontier is adopted to estimate transportation expenditure frontier (TEF). TEFs are treated as unobserved production frontier that influences the actual transportation fee expenditure observed in transportation survey. By utilizing data sets provided by Study on Integrated Transportation Master Plan (SITRAMP, 2004) in Jakarta, households which include person who commute to the target area were extracted. TEFs were estimated for each household life stage category in order to investigate the different constraints of them. From the comparison analysis of TEFs, it was shown that considerable differences in average of TEFs among them in particular larger amount of TEFs is found for single-person and families only with adults. These results mean that the TEF is influenced by household attributes and life environments.
