Abstract

The transition towards Electric Vehicles (EVs) is connecting previously unrelated technologies. We combine an approach to transitions with economic geography, to explore how colocation can support the emergence of coevolution between EV-related sectors. We study technological and geographical relatedness between electric vehicle, battery, smart grid, and combustion engine inventions between 1980 and 2020. Geographical colocation of related technologies can signal coevolution between firms and inventors, that is specifically visible in some classes of cities that we identify. Finally, we fit a multiple regression to estimate the impact of cities’ patenting in related technologies on EV patents. Results show increased relatedness inside cities and growth of colocation in time between electric vehicle, battery, and smart grid patents, demonstrating that relatedness is dynamically evolving during transitions. We also find that combustion engine capabilities are still relevant to support this transition, suggesting path interdependence between cities’ innovative sectors.

城市电动汽车过渡的出现：技术与空间共同发展的案例？

向电动汽车（EV）的过渡正在将以前互不相关的技术连接起来。我们将过渡方法与经济地理学相结合，探索同地定位如何支持电动汽车相关部门之间的共同发展。我们研究了 1980 年至 2020 年间电动汽车、电池、智能电网和内燃机发明之间的技术和地理关联性。相关技术在地理位置上的聚合可能预示着企业与发明者之间的共同演化，这在我们确定的某些城市类别中尤为明显。最后，我们通过多元回归估计了城市相关技术专利对电动汽车专利的影响。结果显示，城市内部的相关性增加了，电动汽车、电池和智能电网专利之间的同地时间增长了，这表明相关性在转型期间是动态发展的。我们还发现，内燃机能力仍与支持这一转型相关，这表明城市创新部门之间存在路径相互依存关系。
