Input-output tables are the cores of input-output analytical techniques. It requires much of time and labor to collect data for the input-output tables. Thus it usually costs 2 or 3 or more years to complete and release the input-output tables of the year, which is called as the famous 'Delay Problem' for the input-output tables. For this problem, researchers have to make an assumption that the direct consumption coefficient keeps stable for a long time when conducting the analysis of input-output, which is obviously against the real economic development.

The research team led by Professor WANG Huiwen firstly discusses the change rule of the direct consumption coefficient and input-output values, combine the forecasting technique for time series with a matrix transformation technique, develop a new method to update input-output tables. It has shown that the comprehensive performance of the new method is better that other methods, which provide a more efficient method for the work of input-output tables.

Under the title of ' Updating Input-Output Tables with Benchmark Table Series,' this study publishes in the journal of 'Economic Systems Research' (impact factor: 3.605, ranked 10/333 in economics in JCR in 2015) online.
