For years, economic growth rates have been high in the western region and low in the eastern region. But in the first quarter of this year such pattern is changed. The export-oriented coastal provinces are now raking in the middle and top. ANBOUND research team points out that the change of economic growth rate on one hand shows that the relatively extensive economic growth in middle and western region lacks motive force; on the other hand, it shows structure adjustment in eastern areas has taken effect. Whether such tendency will continue is worth of the market's attention.
