Abstract:

Riverbasin economy is a kind of regional economy which takes water system as axis.Its development has a major impact on the national economy,and its research provides a new perspective to regional exploitation. In theory,according to endogenous growth theory,using the CobbDouglas productive function,we built an economic growth framework of river basin,including advances of technology,capital investment and human capital as endogenous factor.In practice,taking the Yangtze River as a sample region,the article measured the effect of productived factors that promoted economic growth among the upper,middle and lower river basin by using econometrics of panel data.The result showed that the degree of productive factors influence was different with different areas.Furthermore,it showed gradient effects obviously.Namely,technological progress and human capital contribution to economic growth increased  along the river;while physical capital was just converse. Based on these findings,the article proposed policy recommendations to narrow the economic imbalance in river basin,mainly including: promoting human resources development in the upper riverbasin, implementing of riverbasin development strategy and promoting riverbasin urbanization
