This paper investigates the effects of a tariff reduction on the grain self-sufficiency and the sustainability of domestic grain production. We develop a theoretical model in which trade, tariff, and supply-demand equations are explicitly included, with the classification of food importing and exporting countries. Estimation results based on panel data for 150 countries over 17 years show that ...

As a design theory on energy-saving housing, Self-sufficiency house is suited to the environment conditions of cold rural areas in China. Investigation residence form and energy use important foundation carry out research practice self-sufficiency house. Taking Beijing its surrounding as target, paper combs current situation technical requirements based perspective. After surveying general resi...

As energy systems globally are transitioning into renewable energy, simultaneous targets of high self-sufficiency have led to complex system design proposals. While conventional technology solutions would reduce the complexity in theory, limitations potential outcome may exist. To address this dilemma, work quantified systemic value provided by a solution; biomass combined heat and power (CHP) ...
