Technology Adoption and Critical Mass: The Case of the U.S. Electric Vehicle Market
研究美国都市区电动汽车采纳与充电站部署的相互依赖关系，发现超半数都市区面临临界质量约束，针对这些地区的补贴政策比统一政策更有效。
The interdependence between electric vehicle (EV) adoption and charging station deployment could lead to multiple equilibria. Under certain market conditions, the issue of critical mass arises and a market failing to overcome this hurdle would revert to a no‐adoption outcome. Using panel data of EV sales and charging stations across U.S. Metropolitan Statistical Areas (MSA's), we find that more than half of the MSA's face critical mass constraints and that a subsidy policy targeting these critical‐mass constrained MSA's could be much more effective in promoting EV adoption than the current uniform policy.
