六、 报告摘要：

This paper proposes a nonparametric test for structural changes in linear regression models that allows for serial correlation, conditional heteroskedasticity and time-varying variance inerror terms. The test requires no trimming of the boundary region near the end points of the sample period, and requires no prior information on the alternative, what it requires is the transformed OLS residuals under the null hypothesis. We show that the test has a limiting standard normal distribution under the null hypothesis, and is powerful against single break,multiple breaks and smooth structural changes. We advocate using a wild bootstrap method to improve its size performance in fi…nite samples. Finally, a Monte Carlo experiment is conducted to highlight the merits of the proposed test relative to other popular tests for structural changes.
