Innovation and the Creative Destruction of Trade: A Study of the Intensive and Extensive Margins of Trade for French Firms
研究了法国出口企业的创新对贸易集约边际和扩展边际的因果影响，发现创新主要通过集约边际促进出口，且创新有助于企业在出口市场中生存。
Abstract Our study of French exporters examines the causal relationship between innovation and extensive and intensive margins of trade using a propensity score matching and difference‐in‐differences approach. Results show innovation has a positive impact on total exports driven primarily through the intensive margin. To understand the absence of an extensive margin effect, we show new and terminated product–country transactions increase at similar rates in the year of innovation for the treated and control groups but net trade creation for innovators outstrips that of non‐innovators in the following two years implying firms need to innovate in order to survive in export markets.
