We study how investor composition is related to future return, trading volume, and price volatility in the cross- section of the music-content non-fungible tokens (music NFTs). Our results show that the breadth of NFT ownership negatively predicts weekly collection-level median-price returns and trading counts. In contrast, ownership concentration and the fraction of small wallets are positive predictors. The fraction of large NFT wallets is a bearish signal for future collection floor-price returns. Investor composition measures have weak predictive power on price volatility. Further analysis indicates that an artist’s Spotify presence moderates the predictive power of investor composition for future NFT returns and trading volume, consistent with the notion that reducing information asymmetry helps improve price efficiency.

Many corporate executives believe blockchain technology is broadly scalable and will achieve mainstream adoption, yet there is little evidence of significant shareholder value creation associated with corporate adoption of blockchain technology. We collect a broad sample of firms that invest in blockchain technology and examine the stock price reaction to the “first” public revelation of this news. Initial reac- tions average close to +13% and are followed by reversals over the next 3 months. However, we report a striking differ- ence based on the credibility of the investment. Blockchain investments that are at an advanced stage or are con- firmed in subsequent financial statements are associated with higher initial reactions and little or no reversal. The results suggest that credible corporate strategies involving blockchain technology are viewed favorably by investors.

Blockchain mania occurs in response to the quick rise of Bitcoin price in markets with cryptocurrencies circulation. However, Chinese government policies regarding the development of blockchain are inconsistent--block access to the offerings and exchanges of cryptocurrencies such as Bitcoins, but raise the blockchain technology to a strategic position. We empirically investigate whether the government’s inconsistent policies will lead to blockchain mania and how it affects the blockchainrelated firms’ activities and performance. Our results are threefold: First, the supportive policy can fully offset the negative effect due to the national boycott of cryptocurrencies. Second, Nonspeculative firms experience a stronger and long-standing positive reaction, while the effect on Speculative firms is transient and vanishes after receiving a definitive warning ten days later. Third, the market reaction to government support appears more pronounced among firms having established blockchain technology alliances, or being endorsed officially.

Establishing a comprehensive risk management system and establishing a sound and effective internal control mechanism are important conditions for the survival and healthy development of enterprises. Enterprises should continue to innovate their internal control mechanisms, continuously improve and strengthen their internal control and risk management functions, continuously improve their internal control effectiveness, and assist in high-quality development of enterprises. The article elaborates that the digital transformation of auditing helps to achieve internal audit goals and improve the effectiveness of internal control; Blockchain technology, due to its excellent characteristics of distributed decentralization, authenticity, transparency, and tamper resistance, will help transform the methods of financial and accounting business and audit supervision; The application of blockchain technology in the field of auditing will inevitably lead to the reshaping of audit work models; Blockchain technology will become a trigger point for the audit revolution, comprehensively empowering audit and risk management work. The article introduces JD's blockchain ABS standardization solution, while Tencent and TCL Group's industrial blockchain solve the reliable transmission of trust and value at low cost, confirming that the close combination of blockchain technology with enterprise finance and auditing can assist internal control and play an important risk prevention and control role in enterprise operations. The "blockchain+audit" can achieve online real-time audit, risk assessment and warning, and data analysis becomes the core of audit content; Blockchain+auditing will become an important tool for internal control and risk management in enterprises.

The improvement of production efficiency and the change of business model brought about by the deep integration of the digital economy and the real economy have become an important driving force for industrial transformation and upgrading. This paper explains the necessity of digital transformation of manufacturing, the trends, paths and six technologies of financial digital transformation. In the digital era, relying on data, scenarios, and algorithms to explore the essential logic of business, make predictions and decisions based on business insights, and put forward higher requirements for financial empowerment business. As an important way for enterprise management transformation and upgrading, the core goal of financial digital transformation is to take "data-driven" as the main line, promote transformation based on the two principles of industry-finance integration and in-depth scenarios, and build "value-creating" finance, that is, based on the integrated application of digital technology, so that finance can expand the functions of supporting strategy, assisting decision-making, empowering business, preventing and controlling risks, lean management, operational excellence, quality and efficiency, compliance supervision and other functions on the basis of basic transaction accounting functions, and promote and even lead the value creation functions of enterprises. The article points out that the manufacturing industry should take enhancing competitiveness as the direction, financial management as the center, and improving quality and efficiency as the goal to accelerate digital transformation. Introduced Midea Group's financial digital transformation practices and results.

本文利用2015-2021年的公司层面数据，将链上数据与公司基本面以及资产估值联系在一起。这是一项开创性的、大样本的研究。我们发现，季度同比的区块链数据增长（BDG）包含了公司价值信息，能够预测公司资产增长、销售增长、ROA、标准化意外盈利（SUE）以及专利创新产出。BDG也可以预测股价回报，尤其是在未来盈余公告发布的时间段。基于此构建的BDG多空组合能产生年化10.56%的回报。BDG的预测能力是稳健的，在考虑了行业、地区以及其他短期预测因子之后；BDG的预测能力在国际样本中同样能展现出来。本文进一步讨论了背后的经济机制（例如，持续信息披露以及信息不对称的减少）。异质性分析显示，信息不对称更高、披露质量更低、行业竞争更强、公众信任更低的公司，能从区块链以及链上数据增长中获得更多的收益，主要体现在公司运作和融资方面。

With growing awareness of sustainability, the field of Environmental, Social and Governance (ESG), has been attracting mainstream investors and researchers. Many previous studies have found inconclusive or mixed results on the relationship between ESG ratings and firms’ financial performance, which are mainly attributed to their varied markets, time horizons, and sources of ESG rating. Based on evidence from an emerging market, namely China, this paper examines whether ESG is an adequate indicator for firms’ future financial performance. Given the divergence in ESG rating methodologies, we use ESG data from two ESG rating agencies, one based in China (SynTao) and the other based in Switzerland (RepRisk), for robustness. Specifically, we investigate 377 China A-share companies covered by both agencies and find that ESG rating, albeit divergent due to disparate methodologies, is instrumental in predicting the trend of corporate financial performance (CFP). This work verifies that the forward-looking nature of ESG makes it crucial for firms’ long-term valuation and financial performance in emerging markets. Throughout the research, we observe four issues in the current ESG rating process: the opacity and inaccessibility of source data, the obscurity of ESG rating methodologies adopted by rating agencies, the lack of automated pipeline, and the unannounced historical data rewriting. We believe that the public blockchain ecosystem is promising to address these issues, and we propose future research on the ESG framework for blockchain to call for sustainability focus on this emerging technology.
