In this study, we consider the problem of testing for a parameter change in dynamic panel models with fixed effects. As a test, we suggest using the CUSUM test based on the score vectors and show that under regularity conditions, the test converges weakly to the supremum of a Gaussian process. The test is then compared with the location-scale CUSUM (LSCUSUM) test through Monte Carlo simulation, showing its superiority to the LSCUSUM test. We also conduct a real data analysis using the real energy consumption data of OECD countries along with their GDPs for illustration.
