空间面板门槛模型的Matlab操作
一、前言
下载sarregime_panel、f_sar2_panel、f2_sar2_panel、prt-spreg和demo-file来估计具有两种状态(两种不同系数的空间滞后)和具有空间和/或时间段固定效应的空间面板数据模型(N个区域*T个时间段)。

ABSTRACT：This research proposes a two-regime spatial Durbin model with spatial and time-period fixed effects to test for political yardstick competition and exclude any other explanation that might produce spatial interaction effects among the dependent variable, the independent variables, or the error term. The study also derives the maximum likelihood estimator and variance–covariance matrix of the parameters of this model. Data pertaining to welfare spending by 93 departments in France during 1992–2000 provide significant empirical evidence in support of political yardstick competition. Departments governed by a small political majority mimic neighboring expenditures on welfare to a greater extent than do departments governed by a large political majority.
