Systematically identification and building of digital capability in the Digital Age are of great significance to the obtainment of enterprises’ sustainable competitive advantages. This article first proposes typical application paradigms for the general framework of building digital capability of industrial enterprises in the Digital Age (FBDC) announced as international standard. Then data of over 4100 practical cases of building digital capabilities using FBDC by over 4000 Chinese industrial enterprises are collected. Based on the data, major directions, core implementations of digital capabilities building are systematically demonstrated through statistical analysis. Furthermore, we divide the investigated enterprises into different groups by sector, then organize in-depth research works to illustrate the major directions and typical practices of building digital capabilities in China's raw materials sector, equipment sector, and consumer goods sector. The results show that the major concerns of Chinese industrial enterprises building digital capabilities are centered on six aspects: R&D and innovation, production management and control, supply chain management, financial management and control, business management, and customer service. The results of sector-wise analysis also provide practical reference to industrial enterprises and other stakeholders to identify suitable digital capability based on information and communication technologies application in the Digital Age and efficiently implement the digital capability building process.

With the continuous innovation of new-generation information technology and its accelerated integration with manufacturing industry, industrial internet platforms (IIPs) are rapidly emerging worldwide. Construction and application of IIP has become a new focus in international competition for leading enterprises, and also a new direction of industrial development for many countries worldwide. However, the development of IIP is still in the stage of exploration, and the industry sector still lacks unified understanding of the IIP. Therefore, this study firstly proposes a reference architecture of IIP to clarify its framework and core functions, so as to provide a general reference model for the industry to understand and jointly promote construction of IIP. Secondly, an assessment system is proposed to evaluate the usage of IIP. The assessment framework is composed from three domains namely the foundation, key capability, value and benefit. Finally, the practical value of the reference architecture and the assessment framework of IIP is verified by an industry practice.

Presently, for the purpose of sustainable growth of the economy, it is a common choice to promote sectors’ digital transformation (DT). However, to credibly monitor the effect of DT on sectoral development, it is necessary to develop a systematic measure for the monitoring sector’s DT. This study provides a monitoring index system for sectors’ DT. First, an assessment framework for enterprises’ DT is introduced, which laid a foundation for the proposed monitoring index system for sectors’ DT. Secondly, a monitoring index system for sectors’ DT is established, which includes 13 monitoring indexes from four aspects, namely transformation stages, single-domain digitalization, integration and interconnection, and collaboration, interaction and mode innovation. A weighted method of interval hesitant fuzzy entropy is also given here. Finally, a panorama of sectors’ DT in China is derived by applying the proposed monitoring index system, and a prediction that the level of sectors’ DT in China will continue to grow in the next three years is made by gray predication.

To evaluate the effectiveness of the industrial Internet Platform (IIP) applied by manufacturing enterprises, this study proposes a set of assessment systems for guiding and standardizing the application of IIP. Our assessment framework is established based on five dimensions: strategy and organization; basic conditions; platform application; business innovation; and efficiency and benefit. We collect IIP application data from more than 1400 manufacturing enterprises in China. The application performance of the IIP in manufacturing enterprises were comprehensively analyzed from different perspectives such as equipment on the cloud, industrial knowledge accumulation and reuse, and industrial APP innovative application. The research results show that the overall score of IIP application in China is 31.76 according to our assessment criterion. The breadth and depth of platform application need to be improved. Furthermore, this study provides guidance to a wide range of potential market participants, such as manufacturing enterprises, service providers and relevant policy makers, to assess the effectiveness of platform application.

To build holistic protection against complex and blended network threats, multiple security features need to be integrated into unified security architecture, which requires in a unified threat management (UTM). However, most existing UTMs operate by simply stringing together a number of security applications working independently without system level optimization that streamlines processing flow and leverages shared information and resources to reach high performance. In this paper, a generic framework is proposed to optimize the performance of UTMs at both algorithmic and architectural aspects by exploring the idea of integrated protocol processing (IPP). The algorithm proposed in this paper improves overall protocol processing complexity of ACL and IDS from Theta(log(M) + log(N)) to Theta(log(M +N)) . Experiments on Intel IXP2850 network processor show that our scheme outperforms existing solutions with 30% increase of throughput.
