The industrial Internet represents a fundamental infrastructure for future digitalization, networking, intelligent change, and innovation in the manufacturing industry. In this study, an index system was constructed to evaluate the maturity level of the industrial Internet in the building materials industry.
Based on factor analysis and the entropy weight method, we constructed a method of evaluating the maturity level of industrial Internet for building materials companies. Specifically, an industrial Internet maturity evaluation index system for building materials companies was established through factor analysis, and the weights of various evaluation indexes were assigned using the entropy method. In our study, 59 representative building materials companies were selected as research samples, and empirical research was conducted. Thereafter, one company was selected to verify the evaluation model. Finally, the comprehensive scores and rankings of the 59 building materials companies and their individual scores were calculated.
This study identified seven key indicators for assessing industrial Internet maturity in the building materials industry: data analysis and usage, information network facilities, intelligence level of the system, smart device networking, comprehensive integration, safety management digitization rate, and R & D digitization rate. The study indicated that the majority of large-scale building materials companies were at a 2-star level of industrial Internet maturity, indicating an overall primary stage. The study revealed that information network infrastructure had a relatively high level, but comprehensive integration and data analysis capacity were comparatively weak. Moreover, the R&D digitalization rate and the safety management digitalization rate showed consistent development levels.
This study introduces the first maturity model for the industrial internet in the building materials industry, guiding government decision-making and providing self-assessment direction for companies. It aims to effectively address the industry's challenges of high energy consumption, emissions, labor shortages, and low efficiency.
工业互联网是制造业未来数字化、网络化、智能化变革与创新的基础性基础设施。本研究构建了一套指标体系，用于评估建材行业工业互联网的成熟度水平。
基于因子分析和熵权法，构建了一种针对建材企业工业互联网成熟度水平的评估方法。具体而言，通过因子分析建立了建材企业工业互联网成熟度评估指标体系，并运用熵权法确定各项评估指标的权重。在本研究中，选取了59家具有代表性的建材企业作为研究样本进行实证研究。之后，选取一家企业对评估模型进行验证。最后，计算得出59家建材企业的综合得分、排名以及各自的单项得分。
本研究确定了评估建材行业工业互联网成熟度的七个关键指标：数据分析与应用、信息网络设施、系统智能化水平、智能设备联网、综合集成、安全管理数字化率以及研发数字化率。研究表明，大多数大型建材企业处于工业互联网成熟度的二星级水平，整体处于初级阶段。研究发现，信息网络基础设施水平相对较高，但综合集成和数据分析能力相对较弱。此外，研发数字化率和安全管理数字化率呈现出一致的发展水平。
本研究首次引入了建材行业工业互联网成熟度模型，为政府决策提供指导，并为企业提供自我评估方向。旨在有效应对该行业高能耗、高排放、劳动力短缺和低效率等挑战。
