A theoretical basis for the relationship between the industrial pollutant generation, abatement, emission and economy

This paper attempts to explain the changes of industrial pollutant generation, abatement and emission with economic growth, technology innovation, and industrial structure. All the model variables are assumed as a function of time. Three factors, industrial scale, structure, and generation technologies are considered in pollutant generation model, which together determine the change of pollutant. The average abatement rate, influenced by abatement technologies and the percentage of pollutant generation in each department, is equal to the weighted sum of abatement rate. The change of pollutant emission is commonly determined by the change of pollutant generation and unabatement rate. Particularly, it’s determined by both factors that influence the pollutant generation and abatement rate. The decisive factors of pollutant emission vary with the object investigated.

Theoretical relationship between energy consumption and economic output

ABSTRACT In this study, the theoretical relations among the growth rate of energy intensity, energy consumption, and economic output are inferred and named as the “3GR” model. In some economic entities, the growth rate of energy consumption is equal to the corresponding growth rate of energy intensity and economic output, and their product. Based on the “3GR” model, some conclusions could be obtained: (1) for the expected goal of growth rate of economic output and energy intensity of some economic entities, there is a linear relationship among the growth rate of energy intensity or economic output; (2) for the expected goal of growth rate of energy consumption of some economic entities, there is an inverse relationship between the growth rate of economic output and energy intensity; (3) energy consumption of an economy is equal to the product of the initial level of energy consumption, product of “one plus growth rate of economic output”, and product of “one plus growth rate of energy intensity”.
