文摘By combining non-parameter Z test method for unit root test of time-series with IPS test method for panel data unit root test, we propose a new non-parameter unit root test method for panel data.This method solves the unit root test’s problem that {ε_ it } is L-order auto-correlaiton.Using random simulation method,we compare LL test with non-parameter unit root test for panel data.We found that the non-parameter unit root test is superior to LL test in this case.
