본 연구에서는 시간의 경과에 기반을 둔 누적감가상각비율함수를 이용한 새로운 감가상각방법을 제안한다. 제안된 방법은 임의의 시점에서의 누적감가상각금액을 계산해내는 방법으로, 현재 사용되고 있는 방법들이 가지고 있는 문제점들을 해결할 수 있을 뿐만 아니라, 시간의 경과에 따라 매 회기의 감각상액이 일정하거나, 점차 감소하거나, 점차 증가하는 모든 경우를 체계적으로 계산해낼 수 있다. 이 방법을 사용하면 각 자산의 특성에 맞는 다양한 감각상각형태를 합리적으로 선택하여 사용할 수 있고, 기중에 자산을 취득하거나 처분하는 경우에도 체계적이고 일관성 있게 감가상각비를 상계할 수 있게 된다.

본 연구에서는 이전에 저자가 제안한 감가상각누적비율함수를 이용한 감가상각방법의 실질적인 활용을 위한 보다 상세한 설명을 제시한다. 감가상각누적비율함수는 상각대상금액에 대한 임의의 시점까지의 상각누적비율 값을 제공해 주는 함수로, 시간의 경과에 기반을 둔 감가상각방법에 활용될 수 있다. 이 함수를 사용하면 매 회기의 상각액이 일정하거나, 점차 감소하거나, 점차 증가하는 모든 경우의 상각금액을 체계적으로 계산해낼 수 있어, 각 자산의 특성에 맞는 다양한 감각상각형태를 합리적으로 선택하여 사용할 수 있다. 또한, 상각누적비율이 시간의 연속함수로 표현됨으로써 기중에 자산을 취득하거나 처분하는 경우에도 체계적이고 일관성 있게 감가상각비를 상계할 수 있게 된다. 다만, 함수의 매개변수 값을 얼마로 지정할 것인가 하는 문제가 존재하는데 본 연구에서 그에 대한 자료를 제공한다.

The records system is believed to have started in Italy in the 14th century in line with trade developments in Europe. In 1491, Luca Pacioli, a mathematician, and an Italian Franciscan monk wrote the first book that described double-entry accounting processes. In many countries, including Korea, the government accounting standards used single-entry bookkeeping rather than double-entry bookkeeping that can be aggregated by account subject. The cash-based and single-entry bookkeeping used by the government in the past had limitations in providing clear information on financial status and establishing a performance-oriented financial management system. Accordingly, the National Accounting Act (promulgated in October 2007) stipulated the introduction of double-entry bookkeeping and accrual accounting systems in the government sector from January 1, 2009. Furthermore, the Korean government has also introduced International Financial Reporting Standards (IFRS), and the System of National Accounts (SNA). Since 2014, Korea owned five national accounts. In Korea, valuation began with the 1968 National Wealth Statistics Survey. The academic origins of the valuation of national wealth statistics which had been investigated by due diligence every 10 years since 1968 are based on the 'Engineering Valuation' of professor Marston in the Department of Industrial Engineering at Iowa State University in the 1930s. This field has spread to economics, etc. In economics, it became the basis of capital stock estimation for positive economics such as econometrics. The valuation by the National Wealth Statistics Survey contributed greatly to converting the book value of accounting data into vintage data. And in 2000 National Statistical Office collected actual disposal data for the 1-digit asset class and obtained the ASL(average service life) by Iowa curve. Then, with the data on fixed capital formation centered on the National B/S Team of the Bank of Korea, the national wealth statistics were prepared by the Permanent Inventory Method(PIM). The asset classification was also classified into 59 types, including 2 types of residential buildings, 4 types of non-residential buildings, 14 types of structures, 9 types of transportation equipment, 28 types of machinery, and 2 types of intangible fixed assets. Tables of useful lives of tangible fixed assets published by the Korea Appraisal Board in 1999 and 2013 were made by the Iowa curve method. In Korea, the Iowa curve method has been adopted as a method of ASL estimation. There are three types of the Iowa curve method. The retirement rate method of the three types is the best because it is based on the collection and compilation of the data of all properties in service during a period of recent years, both properties retired and that are still in service. We hope the retirement rate method instead of the individual unit method is used in the estimation of ASL. Recently Korean government's accounting system has been developed. When revenue expenditure and capital expenditure were mixed in the past single-entry bookkeeping we would like to suggest that BOK and National Statistical Office have accumulated knowledge of a rational difference between revenue expenditure and capital expenditure. In particular, it is important when it is estimated capital stock by PIM. Korea also needs an empirical study on economic depreciation like Hulten & Wykoff Catalog A of the US BEA.
