Methodology
Evaluation model • 5 dimensions (Resources, Activities, Network, Environment, Performance) were derived as structuring
  components of the evaluation model, which encompasses the process of input of resources and output
  of economically valuable results.
• Structure of COSTII : 5 dimensions, 13 sectors, and 31 indicators 방법론1

Methodology
• Data collection : The 31 indicators were chosen for their ability to explain occurrences, extent of
  representing sectors, independence, and ease of data gathering.
• Standardization : In order to calculate a composite index and make an international comparison indicators
  were standardized at the same scale to overcome their differences in measurement units and distribution.
  (Re-scaling)
• Missing value : When data is missing in indicators, it is replace by that of the previous year and the one
  before the previous year in case missing value occurs for two years. If data is not available for over two
  years, mean values of the raw data over the last five years are used.
• COSTII composition : COSTII is calculated by the sum of the five dimensions.
  (Its value ranges between 0 and 31) 방법론2
