Applying the new panel unit root test developed in this paper, we can overcome the pitfalls of old‐fashioned panel unit root tests making it possible for researchers testing individual series for a unit root while taking contemporaneous cross‐sectional dependence and structural break into account. The proposed test was used to investigate the status of financial and real integration of China, Japan, UK, the European Union, and the United States based on the empirical validity of real interest parity, uncovered interest parity, and relative purchasing power parity. We found strong evidence in favor of those parity conditions and hence concluded that financial and real integration between China and the other four countries was well established using the new developed panel unit root test while the traditional tests (either univariate or panel) fail to do so. Santrauka Straipsnyje ieškoma rodymų apie finansinę ir realiąją integraciją tarp Kinijos bei jos tarptautinės prekybos partnerių. Autorių patobulinta ekonometrikos metodo (panel unit root test) versija leidžia ekonomistams atsižvelgti į nagrinėjamų šalių tarp šakinių ryšių bei ekonomikos struktūrų specifika. Finansinei bei realiai integracijai tarp Kinijos ir pagrindiniu jos prekybos partneriu, t. y. Japonijos, Jungtines Karalystes, Europos Sąjungos bei Jungtiniu Amerikos Valstijų, vertinti buvo naudoti tokie kintamieji, kaip nepadengtu palūkanų paritetas, palūkanų normų paritetas bei santykinis perkamosios galios paritetas. Tyrimo rezultatai patvirtino prielaida apie gana didelę minėtų paritetų svarba ir leido konstatuoti, kad Kinija yra gana stipriai finansiškai bei realiai integruota su savo pagrindinėmis prekybos partnerėmis.

The Purchasing Power Parity suggests that differences in relative prices in two countries move together with nominal exchange rates in the long run. This study examines the validity of PPP as transition economies for Commonwealth of Independent States (CIS). Purchasing Power Parity holds only when the real exchange rate is stationary in the equation. To test the stationary, we used both time series and panel data analysis. Testing unit root both with time series and panel data in this study, provides us double check of the results. We also test the cross sectional dependence to choose the appropriate panel unit root test. Our test statistics indicate that there is cross section dependence between countries. Hence, one needs to take into consideration the cross section dependence while undertaking unit root tests. Otherwise, the results would be biased. ADF and KPPS indicate that PPP cannot be accepted for the countries except for Russia. According to the panel unit root test results indicate that PPP does not hold for Armenia, Belarus, Georgia, Kazakhstan and Kyrgyzstan except for Russia.
