A major concern of technology-based firms (TBFs) is gaining a competitive edge, for which TBFs develop technologies to embed in their products and services to differentiate themselves from their competitors. TBFs that share similar products or services must compete against each other, which means that business competition among TBFs should be conducted at the product and service levels. However, faced with challenges in obtaining information of the products and services for which TBFs apply their own technologies, previous studies have not thoroughly analyzed the business competition from the perspectives of products and services. Therefore, this study proposes a framework to better understand the business competition among TBFs by linking their business areas and technologies, which refer to products and services in their trademarks, and the technologies described in their patents, respectively. This framework provides the identification of technology-based business portfolios and an understanding of the business competition from both an overall business perspective and within specific areas, considering the technological capabilities and business willingness of the TBFs. This study academically contributes as the first study to conduct a business competition analysis at the product and service levels and industrially contributes by suggesting a systematic process that will help in understanding the rapidly evolving business competition environment.

基于技术的公司（TBF）的主要关注点是获得竞争优势，为此，TBF开发了嵌入其产品和服务中的技术，以使其与竞争对手区分开来。共享相似产品或服务的TBF必须相互竞争，这意味着TBF之间的业务竞争应在产品和服务级别上进行。但是，面对获取TBF应用其自身技术的产品和服务信息的挑战，以前的研究还没有从产品和服务的角度彻底分析业务竞争。因此，本研究提出了一个框架，通过将它们的业务领域和技术联系在一起来更好地理解TBF之间的业务竞争，这些业务领域和技术涉及其商标中的产品和服务，及其专利中描述的技术。考虑到TBF的技术能力和业务意愿，此框架可从整体业务角度和特定领域内识别基于技术的业务组合并了解业务竞争。该研究在学术上作为在产品和服务水平上进行商业竞争分析的第一项研究做出了贡献，并且通过提出有助于理解迅速发展的商业竞争环境的系统过程，在产业上做出了贡献。考虑到TBF的技术能力和业务意愿，此框架可从整体业务角度和特定领域内识别基于技术的业务组合并了解业务竞争。该研究在学术上作为在产品和服务水平上进行商业竞争分析的第一项研究做出了贡献，并且通过提出有助于理解快速发展的商业竞争环境的系统过程，在产业上做出了贡献。考虑到TBF的技术能力和业务意愿，此框架可从整体业务角度和特定领域内识别基于技术的业务组合并了解业务竞争。该研究在学术上作为在产品和服务水平上进行商业竞争分析的第一项研究做出了贡献，并且通过提出有助于理解快速发展的商业竞争环境的系统过程，在产业上做出了贡献。
