中小型开发商产品组合对移动应用质量的影响
The Impact of Small and Medium-Sized Developer Product Portfolios on Mobile Application Performance
摘要: 随着移动应用市场竞争日益激烈，开发商如何通过合理的产品组合提升产品质量成为关键问题。本文基于2019年8月至2021年8月Apple App Store的应用数据，构建2456个移动应用样本组，探讨产品组合特征对产品质量的影响。本文采用了大语言模型与实证研究法进行定量分析，通过PSM匹配减少潜在遗漏变量造成的内生性影响。研究表明，移动应用产品组合的规模和互补性对产品质量有显著的正向影响，而多样性则表现出负面作用。随着产品组合互补性的增强，规模对产品质量的正向影响进一步加强；同时，多样性对产品质量的负向影响会在互补性增加的情况下逐渐减弱。这一发现为中小型开发商在产品组合管理中的战略决策提供了有力支持。
Abstract: With the intensifying competition in the mobile application market, how developers can enhance product quality through strategic product portfolio management has become a critical issue. Drawing on data from the Apple App Store spanning August 2019 to August 2021, this study constructs a sample of 2,456 mobile applications to empirically investigate the impact of product portfolio characteristics on product quality. Quantitative analysis was performed using large language models and empirical research methods, incorporating propensity score matching to mitigate endogeneity caused by potential omitted variables. The findings indicate that the scale and complementarity of a developer’s product portfolio have a significant positive impact on product quality, while diversity in the portfolio exhibits a negative effect. Furthermore, as portfolio complementarity increases, the positive influence of scale on product quality is amplified, while the negative impact of diversity gradually weakens. These insights offer valuable strategic guidance for small and medium-sized developers in managing their product portfolios.
