This paper establishes mixed duopoly game-theoretical models to investigate the economic impacts exerted by privatization in the presence of the environmental pollution. When the residents’ environmental preference is introduced to the public firm’s objective function, we mainly find that...

The mean-risk stochastic mixed-integer programs can better model complex decision problems under uncertainty than usual stochastic (integer) programming models. In order to derive theoretical results in a numerically tractable way, the contamination technique is adopted in this paper for the...

By the field experiment, we research the rice nutrient use efficiency. And the results show that the formulated fertilization can improve the fertilizer nutrient use rate, and N, P2O5, and K2O are improved by 121%, 38%, and 64%, respectively; soil nitrogen level and application rate of nitrogen...
