Resource-based theories propose that firms grow by diversifying into products that use common capabilities. We provide evidence for common-input capabilities, using a policy that removed entry barriers in input markets to show that the similarity of a firm’s and an industry’s input mix determines firm production choices. We model industry choice and economies of scope from input capabilities. When the model is estimated for Indian manufacturing, input complementarities make firms 5% more likely to produce in an industry and are quantitatively as important as time-invariant drivers of coproduction rates. Upstream entry barriers were equivalent to a 9.5% tariff on inputs.

企业的比较优势

基于资源的理论提出,公司通过多样化生产使用共同能力的产品来发展。我们提供了共同投入能力的证据,使用一项消除投入市场进入壁垒的政策来表明公司和行业投入组合的相似性决定了公司的生产选择。我们根据输入能力对行业选择和范围经济进行建模。当该模型针对印度制造业进行估计时,投入互补性使企业在一个行业中生产的可能性增加 5%,并且在数量上与共同生产率的时间不变驱动因素一样重要。上游进入壁垒相当于对投入征收 9.5% 的关税。
