Purpose

This study aims to examine the altering paradigms for two specific characteristics of the international diamond industry: community-based business model and competitive advantage and their impact and interaction effect.

Design/methodology/approach

This study uses global value chain (GVC) analysis to understand the industry characteristics, social impacts and disruption in the international diamond industry. Further, normalized revealed comparative advantage is used to measure the competitiveness of different countries over time. Finally, stochastic frontier analysis is used to test the impact of the community-based business model and competitiveness on exports and estimate the technical efficiency.

Findings

The international diamond industry is witnessing changes in the business model, competitiveness, processes, policies and consumer behavior. While competitive advantage and community have a positive impact on exports, the relationship between competitive advantage and exports gets negatively moderated by the community. Further, insights from the GVC analysis indicate that though the industry is facing several disruptions and challenges, it has shown the unique quality of community reconfiguration and relocation.

Originality/value

This paper provides insights into the diamond industry facing multiple disruptions at various stages of GVC and contributes to the literature on international trade, community-based business models and GVC.

社区商业模式和竞争优势对出口的影响：钻石行业的证据

目的

这项研究旨在研究国际钻石行业两个特定特征的变化范式：基于社区的商业模式和竞争优势，以及它们的影响和相互作用。

设计/方法/方法

这项研究使用全球价值链（GVC）分析来了解国际钻石行业的行业特征，社会影响和破坏。此外，归一化显示的比较优势用于衡量不同国家随时间推移的竞争力。最后，使用随机前沿分析来检验基于社区的商业模式和竞争力对出口的影响，并评估技术效率。

发现

国际钻石行业正在见证商业模式，竞争力，流程，政策和消费者行为的变化。尽管竞争优势和社区对出口有积极影响，但社区对竞争优势和出口之间的关系不利。此外，从GVC分析得出的见解表明，尽管该行业面临着几项颠覆和挑战，但它显示了社区重新配置和重新安置的独特质量。

创意/价值

本文提供了在GVC各个阶段面临多重破坏的钻石行业的见解，并为有关国际贸易，基于社区的商业模式和GVC的文献做出了贡献。
