李宝忠 | 互联网集采平台对企业经营的影响——以河北建设集团为例

李宝忠同学答辩中

▇ 论文摘要：

随着互联网技术的快速发展，互联网集采平台已经成为企业采购领域的一项重要创新。本研究以河北建设集团为案例，旨在探讨互联网集采平台对企业经营的影响，并通过理论综述、案例分析、大样本实证研究以及供应商问卷调查的方式，全面评估了互联网集采平台对企业绩效的影响。

第一章引言部分首先提出了本研究的问题，并介绍了选题的背景与意义。中国建筑行业是一个重要的经济支柱，也是河北建设集团的主要领域，因此本研究对于探讨互联网集采平台如何影响企业经营具有重要意义。同时，本章在研究思路部分概述了本研究的方法和结构。

第二章对互联网集采平台的概念和相关理论进行了深入讨论。采购成本和构成以及集中采购的优势被详细解释。此外，交易成本理论、双边市场理论、规模效应理论等相关理论被应用于研究，以帮助理解互联网集采平台如何影响企业经营。文献综述部分回顾了大型企业的采购管理、采购平台相关研究以及相关文献评述，为后续研究提供了理论支持。

第三章在理论分析和现实观察的基础上，明确了两个研究假设，为后续实证研究奠定了基础。

第四章介绍了研究设计，包括案例分析、大样本实证研究和问卷调查的方法。河北建设集团集采平台的案例分析揭示了平台的基本特征和对企业经营的影响。大样本实证研究通过合成控制法和双重差分方法，以数据来源的支持，为研究结果提供了坚实的基础。同时，问卷调查设计和实证分析也提供了来自供应商的视角，进一步支持了研究结果。

第五章总结了研究结果。首先，通过河北建设集团集采平台案例分析，揭示了平台的基本特征和对企业经营的积极影响。接着，实证研究结果表明，互联网集采平台对企业利润有显著影响，无论是通过合成控制法还是双重差分方法。供应商的问卷调查证据也支持了这一结论。

最后，第六章提出结论，强调互联网集采平台对企业经营的积极影响，并提供了管理建议。研究结果对于河北建设集团以及中国建筑行业的其他企业都具有参考价值，有助于优化采购流程，提高企业绩效，实现更好的经营结果。本研究的发现不仅对企业决策者有指导作用，也为学术研究提供了有关互联网集采平台影响的新见解，为未来研究提供了参考。

▇ ABSTRACT：

Thanks to the rapid development of Internet technology, enterprises make an important innovation and they launch e-centralized procurement platforms (i.e. E-Centralized Procurement Platforms) in procurement activities. Taking Hebei Construction Group for a case study, this paper aims to explore the impact of E-Centralized Procurement Platforms on business operations, and comprehensively evaluates the impact of E-Centralized Procurement Platforms on enterprises’ performance by means of theoretical review, case study, large-sample empirical research, and supplier questionnaire.

李宝忠同学在长江DBA开学活动中

The introductory part of Chapter 1 firstly presents the problems of this paper and introduces the background and significance of the selected topic. Hebei Construction Group is primarily engaged in the construction industry, an important economic pillar of China, so this paper is of great significance in exploring how E-Centralized Procurement Platforms affect business operations. Meanwhile, Chapter 1 outlines the methodology and structure of this paper in the research idea section.

Chapter 2 provides an in-depth discussion of the concept of E-Centralized Procurement Platforms and related theories and explains in detail the procurement costs and components as well as the advantages of centralized procurement. It also implies relevant theories such as transaction cost theory, bilateral market theory, and scale effect theory in the research to help understand how E-Centralized Procurement Platforms affect business operations. The literature review section reviews the procurement management of large-scale enterprises, procurement platform-related studies, and related literature reviews to provide theoretical support for the subsequent research.

Two research hypotheses are specified in Chapter 3 based on theoretical analysis and real-world observation, laying a foundation for the subsequent empirical research.

Chapter 4 makes clear the research design, including the methods of case analysis, large-sample empirical research and questionnaire survey. The case study of Hebei Construction Group's centralized procurement platform reveals the basic features of the platform and its impact on business operations. The large-sample empirical research provides a solid foundation for the findings with the support of data sources through synthetic control method and double difference method. Meanwhile, the questionnaire and empirical analysis also provide perspectives from suppliers, further supporting the findings.

Chapter 5 summarizes the research results. First, the case study of Hebei Construction Group's centralized procurement platform reveals the basic features of the platform and its positive impact on business operations. Next, findings of the empirical research show that E-Centralized Procurement Platforms have a significant impact on corporate profits, either through the synthetic control method or the double difference method. This conclusion is also supported by evidence from supplier questionnaires.

Finally, Chapter 6 showcases conclusions, emphasizes the positive impact of E-Centralized Procurement Platforms on business operations and puts forwards management recommendations. The findings are of reference value to Hebei Construction Group and other players in China's construction industry, helping to optimize the procurement process, enhance enterprises’ performance, and achieve better business results. The findings hereof are not only instructive for corporate decision makers, but also provide new insights for academic research on the impact of E-Centralized Procurement Platforms for future research.
