E-commerce has developed greatly in recent years, as such, its regulations have become one of the most important research areas in order to implement a sustainable market. The analysis of a large amount of reviews data generated in the shopping process can be used to facilitate regulation: since the review data is short text and it is easy to extract the features through deep learning methods. Through these features, the sentiment analysis of the review data can be carried out to obtain the users’ emotional tendency for a specific product. Regulators can formulate reasonable regulation strategies based on the analysis results. However, the data has many issues such as poor reliability and easy tampering at present, which greatly affects the outcome and can lead regulators to make some unreasonable regulatory decisions according to these results. Blockchain provides the possibility of solving these problems due to its trustfulness, transparency and unmodifiable features. Based on these, the blockchain can be applied for data storage, and the Long short-term memory (LSTM) network can be employed to mine reviews data for emotional tendencies analysis. In order to improve the accuracy of the results, we designed a method to make LSTM better understand text data such as reviews containing idioms. In order to prove the effectiveness of the proposed method, different experiments were used for verification, with all results showing that the proposed method can achieve a good outcome in the sentiment analysis leading to regulators making better decisions.

(2019). The flowing tide of parties’ freedom in private international law: party autonomy in contractual choice of law in China. Journal of Private International Law: Vol. 15, No. 1, pp. 234-246.

Under the auspices of the Hague Conference on Private International Law, decades of endeavours brought about the 2019 Hague Judgments Convention, being the newest achievement and a milestone. Serving the basic modern values of promoting access to justice and facilitating multilateral trade, the 2019 Convention reflects the global trend and maximizes the common grounds countries could agree to. As a historical culmination, the 2019 Convention refers to the experience of the past Hague conventions, in particular the 1971 Convention. On the one hand, the 2019 Convention duplicates the 1971 Convention in significant respects, maintaining its virtues; on the other hand, novelties are created to avoid the failures shadowing the 1971 Convention. Overall, the 2019 Convention is acceptable though it falls short of some long-lasting expectations. Recent years have seen China’s efforts to promote transboundary movement of judgments and its contribution to the arrival of the 2019 Convention. As an important global player with increasing ambition of claiming more international presence, the Convention is expected to fare well in China.
