Based on the advance-retreat course model, a growth model under environmental pressure, this paper builds an economic growth model that focuses on the aggregation of capital and innovation with environmental pressure. Importantly, the paper presents methods for computing the optimal quantity of...

This paper puts forward the concept and analytic expression of the environmental pressure index (EPI) for discovering and warning an economic crisis. Empirical researches show, EPI can effectively indicate that the economic crisis occurs or will occur. It is worth noting, EPI can also be applied...

Ambient air pollution kills over four million people every year globally. Improving air quality presents a complex problem for governments as emissions are produced from a wide range of sources and tend to cross boundaries. To understand the challenge of transboundary air pollution transfer, we...

Based on the Solow growth model, this paper builds a combinatorial model for economic growth under environmental pressure. Using the model, the optimal number of industries in an economy can be computed, and the “optimal number” can be regarded as a criterion for decision making concerning...
