In this paper, we make multi-step forecasts of the annual growth rates of the real gross regional product (GRP) for each of the 31 Chinese provinces simultaneously. Beside the usual panel data models, we use panel models that explicitly account for spatial dependence between the GRP growth rates. In addition, the possibility of spatial effects being different for different groups of provinces (Interior and Coast) is allowed for. We fi nd that both pooling and accounting for spatial effects help substantially to improve the forecast performance compared to the benchmark models estimated for each of the provinces separately. It is also shown that the effect of accounting for spatial dependence is even more pronounced at longer forecasting horizons (the forecast accuracy gain as measured by the root mean squared forecast error is about 8% at the 1-year horizon and exceeds 25% at the 13-and 14-year horizons).and Baltagi et al. (2003) for gasoline demand, Baltagi et al. (2000) for cigarette demand, Baltagi et al. (2002) for electricity and natural gas consumption, Baltagi et al. (2004) for Tobin's q estimation, and Brücker and Siliverstovs (2006) for international migration, among others.In addition to pooling, accounting for spatial interdependence between regions may prove beneficial for the purposes of forecasting. Spatial dependence implies that, due to spillover effects (e.g. migration and trade fows), neighboring regions may have similar economic performance and hence location matters. However, the number of studies that illustrate the usefulness of accounting for (possible) spatial dependence effects across cross sections in the forecasting exercise is still limited. For example, Elhorst (2005), Baltagi and Li (2006), and Longhi and Nijkamp (2007) demonstrate the forecast superiority of models accounting for spatial dependence across regions using data on demand for cigarettes from states of the USA, demand for liquor in the American states, and German regional labor markets, respectively. However, only Longhi and Nijkamp (2007) conduct quasi realtime forecasts for period t + h (h > 0) based on the information available in period t. On the other hand, the forecasts made in Elhorst (2005) and Baltagi and Li (2006) are not real-time forecasts, since they take advantage of the whole information set that is available in the forecast period, t + h.Applications of panel data models accounting for spatial effects for the forecasting of regional GDP are even more limited. To our knowledge, there are only two papers treating this issue, namely that of Polasek et al. (2007), who make long-term forecasts of the GDP of 99 Austrian regions, but do not evaluate their accuracy in a formal way, and Kholodilin et al. (2008), who forecast the GDP of German Länder at horizons varying from 1 to 5 years and evaluate them in terms of the root mean square forecast error (RMSFE).Structural type predictions of future trend output growth for China are made by Holz (2008) and Perkins and Rawski (2008).
