摘要

This paper focuses on global cybercrime issues, aiming to explore various aspects related to network security through a multi - pronged approach.

Firstly, based on spatio - temporal data mining, it analyzes the global distribution of cybercrime. It discovers that regions with weak economic and infrastructure conditions, political instability, and low public cyber - security awareness, such as Afghanistan and Myanmar, are at high - risk of cyber threats. In contrast, European developed countries like Belgium and Finland have a lower risk due to their advanced economy, technology, and sound cyber - security systems. Meanwhile, digital fraud attack rates are on the rise globally, with different growth trends in human - initiated attacks and automated bot attacks.

Secondly, through the cross - national difference analysis method, it examines the effectiveness of security policies in different countries. Germany and Denmark have well - developed cyber - security legal systems, which are effective in preventing and combating cybercrime through clear legal provisions, strict law enforcement, and active international cooperation. However, Afghanistan and Myanmar face challenges such as weak legal enforcement, incomplete legal systems, and lack of international cooperation in cyber - security policies.

Thirdly, by using mean - difference and significance tests for population indicators analysis, it reveals that economic indicators like GDP and GNI are significantly different between countries with low and high cyber - crime rates. Higher - income countries generally have more resources for cyber - security construction, resulting in a lower cyber - crime rate.
Finally, a new global cyber - security effectiveness index (GCEI) is created, which
