As an underlying and backbone technology of Bitcoin, Blockchain attracted extensive attention worldwide in recent years due to its unique characteristics of decentralization, openness, immutability, anonymity, etc., which enables it to build a trust basis through recording the point-to-point decentralized transactions in an immutable way via the attached timestamp, thereby improving system efficiency and reducing the cost without relying on the central agent. As it is considered to be a potentially revolutionary technology, Blockchain has been introduced into various industrial fields including finance, supply chain, manufacturing, healthcare, energy, and smart city. In this paper, we conduct a state-of-the-art survey of industrial Blockchain in terms of published articles between 2017 and 2020, and worldwide Blockchain movement including North America, Europe, and the Asia Pacific region so far. We conduct a statistic analysis of the collected articles in terms of three dimensions, which are year of publication, leading research institutes and researchers, and article classification to present a multi-dimensional trend or conclusion. Besides, we analyse articles that are cited over a certain number of times in detail to investigate the hot research directions. Finally, the challenges, opportunities, and future perspectives are discussed to summarize the main obstacles of industrial Blockchain and identify the open research questions in the near future.

作为比特币的基础和骨干技术，由于其独特的去中心化，开放性，不变性，匿名性等特征，近几年来，区块链在全球引起了广泛关注，使其能够通过记录点对点来建立信任基础。通过附加的时间戳以不变的方式进行分散交易，从而提高了系统效率并降低了成本，而无需依赖中央代理。由于区块链技术被认为是一种潜在的革命性技术，因此已被引入包括金融，供应链，制造业，医疗保健，能源和智慧城市在内的各个工业领域。本文针对2017年至2020年发表的文章对工业区块链进行了最先进的调查，到目前为止，全球区块链运动包括北美，欧洲和亚太地区。我们从三个方面对收集到的文章进行统计分析，即出版年份，领先的研究机构和研究人员以及文章分类，以呈现多维趋势或结论。此外，我们将详细分析被引用次数超过一定次数的文章，以研究热门研究方向。最后，讨论了挑战，机遇和未来前景，以总结工业区块链的主要障碍并在不久的将来确定开放的研究问题。领先的研究机构和研究人员，以及文章分类以呈现多维趋势或结论。此外，我们将详细分析被引用次数超过一定次数的文章，以研究热门研究方向。最后，讨论了挑战，机遇和未来前景，以总结工业区块链的主要障碍并在不久的将来确定开放的研究问题。领先的研究机构和研究人员，以及文章分类以呈现多维趋势或结论。此外，我们将详细分析被引用次数超过一定次数的文章，以研究热门研究方向。最后，讨论了挑战，机遇和未来前景，以总结工业区块链的主要障碍并在不久的将来确定开放的研究问题。
