中文摘要
      研究不依赖于具体函数形式下电能-环境协调监管中政府偏好因子的度量问题。运用福利经济学得到该因子的经济意义与内涵;然后推导出偏社会福利要素弹性,将其嵌套到社会福利最大化数学模型的库恩-塔克条件中,得到政府偏好因子可度量的表达式。发现该因子与要素产出弹性及其投入数量相关,且具有动态性。实证研究表明,1995-2004年西部地区对环境存在相对稳定的偏好。并通过检验验证了理论模型的有效性。
英文摘要
      This paper explores quantification of government preference factor (GPF) in electricity-environment coordinated regulation system. Based on social welfare economics, it articulately depicted GPF’s qualitative concept and economic meaning. Then, applying functional analysis, the paper deduced a partial-social-welfare elasticity, and built a mathematics model of maximizing social welfare. By nesting this elasticity into the model’s Kuhn-Tucker condition, it obtained GPF’s definition formula. Through solving the Kuhn-Tucker condition, it got GPF’s quantitative formula, which solved the problem of hard to quantify regulator’s preference in its regulated field. The result shows that GPF only has a relationship to subsystems’ output elasticity and input quantity, and has a dynamic feature. Finally, it provided an empirical research based on the western region of China from year 1995 to 2004. It reveals that government has a stability preference to mitigating pollutants. And validity test confirms that the empirical result fits well to the theoretic model.
