While the extant innovation literature has provided extensive evidence of the so-called “demand-pull” effect, the possible diverse impact of demand evolution on product vs process innovation activities has not been yet investigated. This paper develops a formal model predicting a larger inducing impact of past sales in fostering product rather than process innovation. This prediction is then tested through a dynamic microeconometric model, controlling for R&D persistence, sample selection, observed and unobservable individual firm effects and time and sectoral peculiarities. Results are consistent with the model and suggest that an expansionary economic policy may benefit the diffusion of new products or even the emergence of entire new sectors.

需求在促进产品与流程创新中的作用:模型和实证检验

虽然现存的创新文献已经为所谓的“需求拉动”效应提供了广泛的证据,但尚未研究需求演变对产品与流程创新活动可能产生的不同影响。本文开发了一个正式模型,预测过去销售在促进产品而不是流程创新方面的更大诱导影响。然后通过动态微观计量经济学模型测试该预测,控制研发持续性、样本选择、观察到的和不可观察的个体公司效应以及时间和部门特性。结果与模型一致,表明扩张性经济政策可能有利于新产品的传播,甚至有利于整个新部门的出现。
