通过这项研究，我们希望检验众所周知的“Verdoorn定律”的有效性，该定律考虑了1995-1999年期间葡萄牙经济在地区和部门层面的生产率增长与产出之间的关系（NUTs II）。还检验了Verdoorn定律最初说明中的一些附加变量的重要性，如贸易流动、资本积累和劳动力集中。这项研究的主要目的是确认规模经济的存在，这种经济是两极分化过程的特征，具有累积因果关系性质，解释区域差异。通过在Verdoorn定律的原始规范中引入新的变量，我们打算考察与极化（凯恩斯传统）和集聚（空间经济学传统）现象相关的因素对规模经济的影响。基于面板估计的回归分析结果表明，Verdoorn定律的原始描述更具稳健性，并证实了在区域和部门两个层面上都存在规模经济增长。然而，与贸易流动、资本积累和劳动力集中有关的其他变量对规模经济的绩效影响很小(1)(Martinho，2011)。

英文摘要：
With this study we want to test the validity of the well known "Verdoorn's Law" which considers the relationship between the growth of productivity and output in the case of the Portuguese economy at a regional and sectoral levels (NUTs II) for the period 1995-1999. The importance of some additional variables in the original specification of Verdoorn's Law is also tested, such as, trade flows, capital accumulation and labour concentration. The main objective of the study is to confirm the presence of economies to scale that characterise the polarisation process with cumulative causation properties, explaining regional divergence. By introducing new variables to the original specification of Verdoorn's Law we intend to examine how the economies to scale are influenced by the consideration of factors related to the Polarisation (Keynensian tradition) and Agglomeration (spatial economics tradition) phenomena. The results obtained from the regression analysis based on panel estimation show that the original specification of Verdoorn's Law is more robust and confirm the presence of increasing economies to scale at both, regional and sectoral levels. However, the additional variables related to trade flows, capital accumulation and labour concentration have few influence on the performance of economies to scale (1)(Martinho, 2011).
