document. Libraries such as TextBlob and VADER
in Python can help a researcher perform sentiment
analysis. For example, a researcher can use TextBlob
to calculate the emotional tendencies expressed in a
document to understand the emotional colour of the
document. Entity recognition is an important task in
NLP that can help researcher to identify and
understand specific entities and concepts in policy
documents. SpaCy library in Python has a powerful
entity recognition feature that can be used to extract
entities such as names of people, places,
organisations, and so on from documents. However,
NLP techniques still face some challenges in policy
document processing, such as language specificity
and differences in cultural backgrounds, complex
sentences and semantic ambiguity. Future research
needs to further explore how to improve the accuracy
and generalisation of NLP techniques in policy
document processing.
In general, policy orientation uncertainty
increases enterprise risk exposure, and cross-border
e-commerce faces different national policies,
regulations, customs clearance rules and other
environments due to the fact that the two parties'
transaction subjects are located in different
international market environments; therefore, in the
face of the pressure of sudden changes in the
international economic and trade environment, cross-
border e-commerce needs to improve the efficiency
and accuracy of judging the policy orientation, yet
cross-border e-commerce, often due to the differences
in geographic cultures, is often not able to However,
cross-border e-commerce companies often cannot
accurately understand the precise intention of the
policy due to the differences in regional cultures, and
thus need the advantage of objectivity and cross-
culturalism of AI technology in text analysis and
processing to enable the enterprises to make more
accurate judgments, and the policy and technology
can form a benign circle here, where the policy
creates the conditions for the use of the technology
and the efficient application of the technology feeds
back to the achievement of the policy objectives,
which together contribute to a more resilient global
supply chain network that is more able to withstand
the winds and waves.
2.2 Research in the Context of the
Epidemic
Since the first case was declared at the end of 2019,
as of 11 May 2025, 777,825,189 COVID-19 cases
have been reported globally, and the number of deaths
has come to 7,095,903 (data from WHO). Supply
chains in almost all industries worldwide have been
severely disrupted by the COVID-19 outbreak, with
drastic shifts in demand triggered by the outbreak The
dramatic change in demand triggered by the epidemic
and the ad hoc policies introduced by governments in
response to the outbreak were the core triggers of the
supply chain disruptions.
Epidemic-induced surge in epidemic prevention
materials and stagnant sales of non-essential goods
are more significant in cross-border e-commerce, and
AI technology can improve supply chain agility by
using intelligent forecasting and demand
management. Shen (Shen & Sun, 2023) et al.'s
analysis of JD's case shows that JD's intelligent
forecasting platform achieves a dynamic response to
unexpected dynamic response to demand.
Meanwhile, in cross-border scenarios, such
technology can be further upgraded: first, AI can
integrate data such as overseas social media public
opinion, customs policy changes, and local logistics
timeliness to build demand prediction models for
different countries. For example, when an epidemic
breaks out in Europe and the US, the AI system warns
of a surge in demand in advance by crawling the
search volume of masks on Amazon, eBay and other
platforms in real time, and guides domestic stock
preparation. Secondly, for slow-selling products due
to the epidemic, JD launched promotional campaign
to reduce unhealthy inventory, while AI can analyse
the differences in demand in different markets, thus
effectively reducing backlog inventory, ensuring the
return of funds, and maintaining the stability of the
supply chain. Finally, AI can automatically adjust the
replenishment cycle of cross-border goods based on
the output of the prediction model, compressing the
traditional 6-8 week cross-border replenishment
cycle into 72 hours, effectively alleviating the
"bullwhip effect".
Epidemic-induced international capacity
shortages and border controls often lead to cross-
border e-commerce supply chain disruptions, and this
core pain point has been previewed in the JD Wuhan
regional distribution centre disruption. However, JD
used the network optimisation capability of the JD-
NetSIM system to respond quickly and solve the
supply chain disruption problem. For example, in
2020, when the US-China air transport shutdown
prevented some goods from being delivered, JD's AI
system automatically initiated alternatives, such as
shipping goods from Shenzhen port to Los Angeles
by sea, and then distributing them to Amazon's FBA
warehouse through the trucking paths calculated by
AI, which resulted in a delay of 48 hours in the
timeframe, despite the increase in cost. During the
