基于增长极理论的国家级新区发展差异研究——以上海浦东新区、天津滨海新区为例

Research on the Difference in the Development of State-level New Districts Based on Growth Pole Theory——A Case Study of Pudong New District of Shanghai and Binhai New District of Tianjin

自1992年上海浦东新区成立以来,我国已相继批复设立浦东新区、滨海新区等十九个国家级新区。新区被赋予带动所在区域发展的重任,属于区域增长极。增长极的作用不应只包含极化效应,更重要的是涓滴效应。文章选取北京大学杨开忠提出的"加权变差系数"进行发展差异程度的衡量,得出两直辖市区域内差异程度同样在扩大的结论。发现系数变化以及系数自身的绝对值大小也有较大差异,最终得到了区域经济增长短期可以依靠增长极刺激,但长期终将回归潜在的自然增长速度的结论。

Nineteen state-level new districts including Pudong New District and Binhai New District have been officially approved in succession since the foundation of Pudong New District of Shanghai in 1992. State-level new districts, as the growth pole, undertake the mission of pushing forward the regional development. However, in growth pole theory, trickle-down effect turns to be more important compared with polarization effects. The paper measures the degree from deviation by weighted variation coefficient, which was presented by professor Yang of Peking University, and concludes that the differential interpretations of both cities are enlarging. Whafs more, when it comes to the variation and absolute value of the coefficient, districts are different as well. This paper draws a con-clusion that growth poles could drive the regional economic development in a short term ; however, in a long term, it will get back to what it is supposed to be.
