Gross Regional Domestic Product (PDRB) is one of the tools of economic data that can be used to evaluate the economic development performance of a region (province and district / city). These data sets may also be used for other purposes, such as the basis for the development of economic models in order to formulate policy formulations, the rate of velocity of money, the deepening of the financial sector, taxation, export studies and import and so on. According to macroeconomic theory, the calculation of GRDP can be done through three approaches, namely : production / supply (GDP by Industry / industry) approach, final expenditure approach (GDP by Expenditure) and income approach (GDP by income) . The three calculation approaches will in theory produce the same GDP.
