Design of green-structural keynesian investment multiplier model based on second-stage input-output technique and its application

In order to promote the application value and instruction significance of “structural Keynesian investment multiplier” (abbreviated as SKIM), this paper takes environment consumption and environment input into the second-stage input-output table. It meanwhile proposes a concrete plan of compiling a “second-stage input-output table that incorporates environment factor”, and based on this designs a “green structural Keynesian investment multiplier” (abbreviated as G-SKIM). Empirical analysis of 42 different industries shows that except some clean industries without pollution, every other industry has more or less a lower G-SKIM than that of corresponding general SKIM. This difference between the two multipliers reflects the level of environment consumption induced by investment in the process of production.
