二战后,就经济增长模式来说,从空间角度看,区域经济增长理论出现两极分化:均衡增长理论和非均衡增长理论两大类。在完全竞争和规模收益不变(或递减)的假定下,在新古典框架中,区域或空间因素只不过是额外引入的一个变量而已,这两种增长理论很难进行整合。20世纪末以来,在垄断竞争和规模收益递增的框架下,西方学者对均衡与非均衡的增长模式进行了有效整合,就区域经济增长提出了一些全新的理论解释和政策含义。
After the Second World War, in terms of economic growth mode, from a spatial point of view, the theory of regional economic growth has shown polarization: the theory of balanced growth and the theory of uneven growth two categories. Given the same (or diminishing) return to full competition and scale returns, in the neoclassical framework, regional or spatial factors are but one additional variable introduced, and the two growth theories are difficult to integrate. Since the end of the 20th century, under the framework of monopolistic competition and increasing returns to scale, western scholars have effectively integrated the balanced and unbalanced growth models and put forward some entirely new theoretical explanations and policy implications on regional economic growth.
