1、据模型定义为,yit=i+Xit'+it,i=,,…,N;t=,,…,T其中i是随机变量,表示对于i个个体有i个不同的截距项,且其变化与Xit有关系;Xit为k阶回归变量列向量包括k个回归量,为k阶回归系数列向量,对于不同个体回归系数相同,yit为被回归变量标量,it为误差项标量,则称此模型为个体固定效应模型。个体固定效应模型的强假定条件是,Eiti,Xit=,i=,,…,Ni作为随机变量描述不同个体建立的模型间的差异。因为i是不可观测的,且与可观测的解释变量Xit的变化相联系,所以称式为个体固定效应模型。.面板数据模型分类个体固定效应模型entityfixedeffectsmodel个体固定效应模型也可以表示为yit=D+D+…+NDN+Xit'+it,t=,,…,T其中Di=其他,,个个体如果属于第,,,,,,Nii个体固定效应模型还可以用多方程表示为yt=+Xt'+t,i=对于第个个体或时间序列,t=,,…,Tyt=+Xt'+t,i=对于第个个体或时间序列,t=,,…,T…yNt=N+XNt'+Nt,i=N对于第N个个体或时间序列,t=,,…,T注意:在EViews输出结果中i是以个不变的常数部分和随个体变化的部分相加而成。在EViews以上版本个体固定效应对话框中的回归因子选项中填不填c输出结果都会有固定常数项。.面板数据模型分类个体固定效应模型entityfixedeffectsmodel对于个体固定效应模型,个体效应i未知,EiXit随Xit而变化,但不知怎样与Xit变化,所以EyitXit不可识别。对于短期面板数据,个体固定效应模型是正确设定的,的混合OLS估计量不具有致性。下面解释设定个体固定效应模型的原因。假定有面板数据模型yit=+xit+zi+it,i=,,…,N;t=,,…,T其中为常数,不随时间截面变化;zi表示随个体变化,但不随时间变化的难以观测的变量。.面板数据模型分类个体固定效应模型entityfixedeffectsmodel以案例为例,省家庭平均人口数就是这样的个变量。对于短期面板来说,这是个基本不随时间变化的量,但是对于不同的省份,这个变量的值是不同的。上述模型可以被解释为含有N个截距,即每个个体都对应个不同截距的模型。令i=+zi,于是式变为yit=i+xit+it,i=,,…,N;t=,,…,T这正是个体固定效应模型形式。对于每个个体回归函数的斜率相同都是,截距i却因个体不同而变化。可见个体固定效应模型中的截距项i中包括了那些随个体变化,但不随时间变化的难以观测的变量的影响。i是个随机变量。因为zi是不随时间变化的量,所以当对个体固定效应模型中的变量进行差分时,可以剔除那些随个体变化,但不随时间变化的难以观测变量的影响,即剔出i的影响。以案例file:panel为例得到的个体固定效应模型估计结果如下:输出结果的方程形式是tLncp=ˆ安徽+ˆLnipt=–+LnipttLncp=ˆ北京+ˆLnipt=++Lnipt。。tLncp=ˆ浙江+ˆLnipt=++LniptR=,SSEr=,t=,DW=从结果看,北京上海浙江是自发消费消费函数截距最大的个地区。.面板数据模型分类时点固定效应模型timefixedeffectsmodel如果个。
