经济发展与跨技术互动结构

Economic development and the structure of cross-technology interactions

Anton Bondarev, Frank C. Krysiak

摘要:

对经济增长的大多数解释都是基于知识溢出效应,即某些技术的发展促进了其他技术的提高。实证研究表明,这些溢出效应可能具有异质性和相当复杂的结构。但是,到目前为止,很少有人关注这种跨技术互动的不同结构的后果:经济发展更容易由同质或异质互动,由单向或双向溢出促进?通过一个简单的增长模型,详细描述了一个具有跨技术相互作用的研发部门,我们分析了溢出效应的结构如何影响增长前景和增长模式。我们表明,某些类型的相互作用(例如,单向相互作用)不能诱导指数增长,而其它结构可以。此外,根据互动的结构,所有或只有一些技术将有助于长期增长。最后,一些溢出结构可导致复杂的增长模式,如技术转型,随着时间的推移,不同的技术集群成为增长的主要动力。

英文摘要:

Most explanations of economic growth are based on knowledge spillovers, where the development of some technologies facilitates the enhancement of others. Empirical studies show that these spillovers can have a heterogeneous and rather complex structure. But, so far, little attention has been paid to the consequences of different structures of such cross-technology interactions: Is economic development more easily fostered by homogenous or heterogeneous interactions, by uni- or bidirectional spillovers? Using a detailed description of an r&d sector with cross-technology interactions embedded in a simple growth model, we analyse how the structure of spillovers influences growth prospects and growth patterns. We show that some type of interactions (e.g., one-way interactions) cannot induce exponential growth, whereas other structures can. Furthermore, depending on the structure of interactions, all or only some technologies will contribute to growth in the long run. Finally, some spillover structures can lead to complex growth patterns, such as technology transitions, where, over time, different technology clusters are the main engine of growth.
