The Input-Output (I-O) tables are a complete and detailed account on transactions related to production and consumption of goods and services between producers and consumers and its interdependencies among the industries in the market. The I-O tables are the result of the systematic data collection, evaluation and compilation of vast statistical information regarding production and consumption covering a wide range of economic sectors. In the compilation of the I-O tables, all the values are balanced between the supply and demand by industrial sectors so as to ensure the accuracy.
The I-O tables for 2005 are published in two series of publications, Input-Output Tables, Malaysia 2005 and Input-Output Tables Malaysia 2005 (Volume 2). The I-O tables provide information that can be used for impact economic analysis such as output inducement, value added inducement, import inducement as well as economic linkages. The Department of Statistics, Malaysia had published six sets of Malaysia I-O tables for reference year of 1978, 1983, 1987, 1991, 2000 and 2005. The latest I-O tables produced by the Department for reference year 2005 use the concepts and definitions based on the System of National Accounts (SNA), 1993 and Handbook of Input-Output Table Compilation and Analysis (1999) published by United Nations.
