In this study, in order to identify reasonableness and appropriateness of standard cost being newly applied in estimating development cost of development charge, development charge being estimated and charged by comparing development cost based on cost reimbursable that is an existing estimation method with that of a new standard development cost method by each item and applying cost reimbursable was comparatively analyzed by re-estimating it through standard cost method based on Daegu Metropolitan City.
In addition, the objective of this study is to contribute to valid standardized estimation of standard cost by suggesting review items in estimating standard cost in the future for reliability enhancement of the study result through an analysis of correlation between development charge and development cost and its relation with official land price,
As a comparative analysis result of development charge by applying standard cost, first, as average development charge showed significant difference depending on each region, average development charge per each development project was represented to be more heavily imposed than development charge levied on county region by app. 2.75 times and it could be realized that more development gain was generated in the development project of district region rather than county region.
Second, as a comparative analysis of application status for development cost by cost reimbursable, while cost weight of standard cost item of district region was 38.3% but that of county region was 68.6% (cost weight of county region is almost 2 times of that of district region), weight of other expenses of district, county region was represented as 61.7% and 31.4%, respectively (weight of county is app. 1/2 level of district) and so, it could be realized that cost weight by each item of development cost was reflected in opposite way depending on each district and county.
Third, expenses of cost reimbursable for standard cost item showed significant difference per area depending on each region and in case of district region, such expenses was 40,830won/m2 and that compared with standard cost was 23,371won/m2 and it could be realized that district region of Daegu Metropolitan City that is non-capital area was subject to excessively estimated standard cost.
And even in the study result of hypothesis test analyzing correlation between development charge and development cost, it was confirmed that standard cost item of development cost had a relation with district, county region and as a result of analyzing a relation between official land price and development charge, development charge and weighted average official land price were proportional and expenses of standard cost item and weighted average official land price were inversely proportional.
As a result of study, as it was confirmed that current standard cost being applied by just dividing into capital area and non-capital area without considering regional features or weight by each development cost item was oppositely represented even in the same non-capital areas and standard cost of non-capital area was excessively estimated, adjustment for standard cost of non-capital area is considered to be required and differential application of standard cost by each district, county of metropolitan area as well as by capital, non-capital area would be required.
In addition, as development charge and standard cost were represented to have a close relation with official land price, at the time of estimating standard cost, regional factor and weighted average official land price level depending on development degree is required to be considered.
And by continuously managing and analyzing actually charged data being generated by system operation, more concrete and practical standard cost application method reflecting regional features is required to be explored and sustained supplementary study would be required in the future in oder to provide valid improvement method of standard cost system together with a necessity of researching on a new direction for estimation of standard cost and division of application range.
