A Community Satisfaction Model Based on Simultaneous Equations;
基于联立方程的社区满意度模型
We try to research empirically and illustrate the relationship between the environmental and economic performance of firm through building the simultaneous equations and adopting the datas of the European some country and Chinese some region paper industry.
通过联立方程模型把环境绩效和经济绩效结合在一起,并借鉴意大利、荷兰及我国某地区造纸行业的数据进行了实证研究,发现这种方法可以验证环境绩效与经济绩效之间的关系,研究结果比较支持传统学派的观点,但这并不表明修正学派的观点没有价值,只是因为本文只针对一个特殊的行业造纸业,而且考察的只是企业短期的经济绩效,如果考虑环境污染给社会带来的外部成本,那么结果可能相反。

首先分析了联立谱的局部性质，然后基于Ｒａｙｌｅｉｇｈ商理论给出一种求解方案，最后研究扰动理论，建立了Ｇｅｒｓｃｈｇｏｒｉｎ圆盘理论、Ｂａｕｅｒ－Ｆｉｋｅ型定理、Ｗｉｅｌａｎｄｔ－Ｈｏｆｆｍａｎ型定理，证明了联立谱的半连续
Panel data was applied in the analysis and Three-Stage Least Squares was used to make simultaneous equation analysis.
本文通过公司股权集中度与企业业绩的联立模型,对影响股权集中度的主要因素进行了实证分析,在分析中采用面板数据(panel data)并运用三阶段最小二乘法(Three-Stage Least Squares)进行联立分析,弥补了以往的对股权集中度研究的单一截面数据和将股权集中度与企业业绩外生化的缺陷,通过分析发现除了资产规模外的企业业绩、持股主体和行业分布均有显著影响,在取得结论的基础上提出了一些建议。
