The Relationship Between Plant Scale and Product Diversity in Canadian Manufacturing Industries
研究了加拿大制造业中工厂规模与产品多样性的关系，发现较大工厂规模与更高产品多样性相关，且小工厂可通过产品组合弥补规模劣势。
When multiproduct plant economies exist, plant size and diversity decisions are closely linked. The disadvantage of small plant size can be offset by product-packing. The paper shows that within 4-digit industries, larger plant size is associated with greater product diversity. Then a cross-sectional regression at the 4-digit level indicates that Canadian plant size relative to an estimate of US MES is related positively to industry measures of average plant diversity. This suggests that inherent plant scale disadvantages in small economies such as Canada are offset by product-packing.
