ABSTRACT

This paper pilots an approach for using trademark data to study regional diversification. Bridging the respective literatures, we develop a regional trademarking-intensity measure that can shed new light on how different regions diversify while also accounting for changing industrial structures and income levels (regional gross domestic product). The approach reveals that density has a moderate effect on trademarking intensity and confirms the strong relationship between new firm formation and regional diversification. These effects are found to vary by sector and to be sensitive to industry-level employment and turnover. Lastly, the analysis indicates that regional diversification differs sharply between urban and peripheral regions.

摘要

本文试行了一种使用商标数据研究区域多元化的方法。结合各自的文献，我们开发了一种区域商标密集度度量，可以为不同区域如何多样化提供新的视角，同时也考虑到不断变化的产业结构和收入水平（区域国内生产总值）。该方法揭示了密度对商标强度的影响适中，并证实了新公司形成与区域多元化之间的密切关系。发现这些影响因行业而异，并且对行业层面的就业和营业额很敏感。最后，分析表明，区域多样化在城市和周边地区之间存在显着差异。
