To explore the internal driving force of the growth of rice yield per unit area in China, a model based on varying-coefficient production function is proposed in this study, which comes from the idea that the constant elasticity parameters in the Cobb-Do...

Designing aquaculture production units will require decisions on which treatment to include, e.g., the intensification of the system, and then a decision on a technical solution for each treatment function selected to implement. To complicate matters, ea...
