There are three approaches which used, i.e. the location quotient (LQ) to determine the base sector, sectoral typology to determine the prime sector, and overlay of the base sector and prime sector to determine the leading sector. The data analyzed is the gross regional domestic product (GRDP, PDRB) in the year of 2010 to 2016 at 2010 constant market prices.The result of data analysis show that all of the prime sector are as leading sector and not all of base sector as the prime sector. With the overlay method between the base sector and the prime sector, the leading sector are: (1) agriculture, forestry, and fishing; (2) construction; (3) accommodation and food service; and (4) public administration and defence; compulsory social security. However, only one of them as the leading sector among the seven regencies, namely public administration and defense; compulsory social security sector. From the data analysis, all prime sectors are the leading sector and not all base sectors are the prime sector. So, the overlay results indicate that the prime sector as well as the leading sector. Thus, to determine the leading sector simply by using the approach of sectoral typology. |
