AI 中文总结
本研究通过分析Shopify应用生态的多维度数据，揭示其集中度、进入时机与平台治理对应用生存和竞争的影响，发现后期进入者增长更快，平台治理会不对称重塑竞争，应用早期数据可预测退出。
AI 中文摘要
Shopify市场拥有超过16000个活跃第三方应用，服务270万个活跃商家店铺，这些店铺的年销售额估计达7060亿美元，但目前关于其结构和采用驱动因素的实证证据很少。我们使用2025年9月的所有24826个应用的快照、2019年2月至2026年3月共366周的7708个应用的每周面板，以及从互联网档案馆重建的上架历史对其进行分析。在55个成熟功能类别中，超过一半是低集中度类别，20%是高集中度类别，且规模较大的类别始终集中度更低。在分析的50个类别中，88%的类别中，后来进入者的增长速度快于早期进入者，这一情况在7年的季度重新估计中持续存在，早期进入者的净检测安装量减少，而后期进入者的安装量增加。平台治理不对称地重塑了竞争：Shopify进入聊天领域扭转了两年多的去集中化趋势；其Product Reviews应用的弃用，据我们所知是首次测量到的平台所有者从补充品类退出，释放了191000个安装量，其中最多三分之一在一年内重新出现在竞争对手的采用中；2021年平台收入分成的减少未对进入或留存产生可检测的变化。失败在很大程度上是隐性且可预测的：退出应用的中位数峰值为8个检测安装量，在推出后68周内从跟踪中消失，7年内92%的类别发生了领导权更迭，应用前六个月的公开可观测数据可预测两年内的退出，交叉验证的AUC超过0.8。Shopify上的应用市场仍然具有可竞争性；谁受益取决于平台治理和进入条件，而非进入时机。
英文摘要
The Shopify marketplace hosts more than 16,000 active third-party applications, serving 2.7 million active merchant stores generating an estimated \$706 billion in annual sales, yet little empirical evidence exists on its structure and adoption drivers. We analyse it using a September 2025 snapshot of all 24,826 applications, a weekly panel of 7,708 applications over 366 weeks (February 2019 to March 2026), and listing histories reconstructed from the Internet Archive. Across 55 established functional categories, over half were low-concentration and 20\% highly concentrated, with larger categories consistently less concentrated. Later entrants grew faster than early movers in 88\% of the 50 analysed categories, persisting across seven years of quarterly re-estimations, with early movers on net losing detected installations whilst late movers gained them. Platform governance reshaped competition asymmetrically: Shopify's entry into chat reversed more than two years of de-concentration; the deprecation of its Product Reviews application, to our knowledge the first measured platform-owner exit from complementor category, released 191,000 installations of which at most a third reappeared as competitor adoption within a year; the 2021 reduction of the platform revenue share produced no detectable change in entry or retention. Failure is largely silent and predictable: the median exiting application peaked at 8 detected installations and disappeared from tracking within 68 weeks of launch, category leadership changed hands in 92\% of categories over seven years, and publicly observable data from an application's first six months predict exit within two years with cross-validated AUC above 0.8. App markets on Shopify remain contestable; who benefits depends on platform governance and entry conditions more than on entry timing.
