Theoretical analysis of basic coefficients and models of incremental input-output table

Contains comparable input-output tables for four sectors in China (agriculture, industry, construction, and services) in 2015 and 2020, as well as incremental input-output tables calculated based on the first two, sourced from the National Bureau of Statistics. And provide the calculated direct consumption coefficient, direct consumption coefficient increment, input-output growth rate, elasticity coefficient and its incremental direct consumption coefficient data, corresponding to the calculation in Table 5 of paper 2.3.2. Code containing incremental Leontief inverse matrix existence check. This code is written in Matlab language and generates reversible frequency of the matrix under certain conditions (such as limiting the number of departments and the range of matrix elements, specifying the number of cycles, etc.). By setting a larger number of cycles to approximate the probability of reversible incremental production activity coefficient, it helps to illustrate that the matrix is generally reversible.
