寬頻網路對於現在的總體環境變得不可或缺，也是各個國家不斷發展追求的網路技術，寬頻網路普及率是衡量一國家寬頻發展程度的重要指標，本研究將行動寬頻普及率作為主要分析對象。許多國家已經擁有超過100%的行動寬頻普及率，固網寬頻普及率也達到了48%，在市場已經飽和的狀況下繼續發展寬頻市場，容易造成電信業者或營運商收益無法提高，但是也有許多國家是處於行動寬頻普及率相對較低的狀態，例如：南美洲、非洲、東南亞等，國際電信聯盟(ITU)認定其中一些國家為「有潛力的未開發市場」，因此本研究認為若在擁有高行動、固網寬頻普及率國家的電信業者，可以投資於國外市場，以創造營收來源。本研究將利用空間統計、空間計量經濟模型以及空間擴散效果，計算出影響各國家的因素以及各因素的影響權重，分析出較容易受到其他國家影響而提高行動寬頻普及率的國家，即為較適合投資之國家，期望能夠提供電信業者投資海外寬頻市場的依據。

This research objects are exploring whether the mobile broadband penetration rate has spatial dependence in global geographical and use the fixed broadband penetration rate to verify the correlation with mobile broadband penetration rate and abroad market. Broadband internet becomes indispensable to the present environment, also every country's development goal and the essential index that evaluate country development level. Mobile broadband penetration rate had more than 100% in many countries, fixed broadband penetration rate also reached 48%, in these saturated markets, operators’ revenue will be limited. However, there are many developing countries, such as: South America, Africa and South America etc., the International Telecommunication Union (ITU) has identified some of these countries as "undeveloped markets with potential”. This research believes if countries that have high broadband penetration rate can invest abroad telecommunication industry, crate another business model and revenue. In order to explore relationship of telecommunication market between countries, this research will use spatial statistic, spatial econometrics and spatial spillover effect to calculate the impact factors’ level and impact weight. According to the research result. Countries more suitable for investment are more likely to be affected by other countries and increase the penetration rate of mobile broadband. Expecting the results of this study will provide investment advice for telecommunication operators to invest in the overseas broadband market.
