中文摘要：

我国区域差距扩大的困境集中表现为增长极点极化过度和扩散不足并存所引致的“极化陷阱”。从经济学理论来看，非平衡战略福利判别标准中补偿机制的内在冲突是极化陷阱形成的深层原因。以区践差距的分类为基础，补偿机制分为结构性补偿和功能性补偿两种类型。对增长极的过分重视导致了时结构性补偿的偏好，然而结构性补偿所带来的协调空间正在减弱，以全要素生产率增长为基础的功能性协调将成为区域协调的主要力量。因此，形成结构性协调与功能性协调的互补将在促进区域协调发展的同时弱化“极化陷阱”的困境。

英文摘要：

The dilemma of regional gap expansion in China is featured by ＂polarization trap＂ brought about by over - polar- ization of the growth poles and insufficient expansion. From the viewpoints of the economic theories, the underlying reason for the formation of such trap lies in the inside conflicts of the compensation mechanism in the judgment standard of non- balanced strategic welfare. Based on the classification of regional gap, the compensation mechanism can be classified into two types, structural compensation and functional compensation. Too much emphasis on the growth poles leads to the bias to structural com- pensation. However, its coordination space in now reducing, while functional coordination based on total factor productivity growth will become the major force in regional coordination. As a result, the complementation of the two types of coordination will improve regional coordination as well as relieving the pressure of ＂polarization trap＂
