行動寬頻技術標準及授權法律分析 / Standard setting and license issues in the wireless industry沈佩霖 Unknown Date (has links)
行動寬頻技術在21世紀這個人手一機的今日,為一非常重要且背後蘊藏龐大商業利益的產業。正因此等商機,使得行動寬頻技術標準,自2G、3G直到今日即將進入4G以來,始終存在複雜的授權糾紛,包括關鍵技術的認定、合理權利金費率的訂定,以至可能引發之競爭法規範問題,在在都顯示出此產業對人類社會的影響,以及業者、國家對此領域所投注之高度關注。
本論文以2G以來,各個通訊世代所生之授權紛爭為例,分析通訊標準制訂過程將會面臨的問題。並在最後檢視我國通訊產業之結構,就此特性來分析我國通訊業者之優勢與列勢。在行動通訊產業這種具有高度「贏者全拿(Winner takes all)」的領域中,我國業者究竟應如何在此種高度競爭的領域中生存,進而與國際接軌,當為我國政府與通訊業者須認真思考之議題。

從創新擴散理論分階段探討國家寬頻發展影響因素 / Identifying Key Determinants of Broadband Diffusion by Stage Based on Innovation Diffusion Theory林茂雄, Lin, Mao Shong Unknown Date (has links)
寬頻擴散可促進國家之生產力、就業、經濟成長及國家競爭力等,若能精準找出促進寬頻擴散之關鍵影響因素,將有利於政府集中資源有效率地推動寬頻發展。本研究提出研究問題與假說,以Rogers (2003)及Hall (2006)所提出影響創新擴散速率之社經因素、採用成本、採用效益、網路效應、資訊及不確定性及產業環境等6大因素面向為基礎,蒐集OECD國家及台灣等31國家相關資料,挑選Gompertz模型進行固定寬頻擴散Panel資料迴歸分析,發現各因素在全期及不同擴散階段有不同之顯著性與影響程度,表示分階段分析有其必要性。擴散初期之關鍵影響因素為收入、教育水準、平台競爭程度、人口密度及實施LLU累積年度等5項,而擴散後期之關鍵影響因素為寬頻價格、網際網路內容、決定採用時固定寬頻用戶比例、撥接用戶比例及擁有PC家庭比例等5項,可作為政府及業者於不同擴散階段精準投入資源以有效推動寬頻擴散之參考。
本研究續以前述分析結果選取日本、南韓、美國、丹麥、瑞士及台灣進行實際擴散比較,確認前述關鍵影響因素挑選之有效性。擴散初期,台灣有高人口密度優勢,若能提早推動寬頻並推動促進競爭措施,可促進初期之快速擴散。擴散後期,台灣國際排名退步,原因為寬頻價格過高,故此階段政府及業者應特別確保寬頻價格能夠使潛在採用者有能力並願意付費採用,才能促使寬頻持續有效擴散。
最後,本研究採用與固定寬頻相同迴歸分析模型對FTTX及行動寬頻分別進行分析後,有關行動寬頻,教育水準、寬頻價格、決定採用時行動寬頻用戶比例、人口密度、網際網路內容、使用固定寬頻語音服務比例、決定採用時FTTX用戶比例及使用網際網路家庭比例等8項變數有顯著效應;有關行動寬頻,收入、寬頻價格、網際網路內容、決定採用時行動寬頻用戶比例、使用網際網路家庭比例及人口密度等6項變數有顯著效應。因此,政府及業者若擬促進特定寬頻服務發展,仍須針對其服務特性推動特定之政策或策略。其中,寬頻價格、網際網路內容、網路效應及使用網際網路家庭比例等4項因素對FTTX及行動寬頻服務之影響類似,而此4個因素與固定寬頻後期擴散之關鍵影響因素較相近,因此,對於已存在市場的服務,即使是後來以較佳品質或功能之新服務型式提供,新服務之關鍵影響因素仍較接近已存在市場服務關鍵因素。
總之,本研究不同於過去文獻,以創新擴散理論為基礎,以國家層級資料量化分析與探討寬頻擴散之關鍵影響因素,除分別提供政策及管理建議供政府及業者參考外,亦補強Rogers (2003)及Hall (2006)所提出創新擴散理論未釐清與比較創新擴散影響因素在不同擴散階段影響之不足。 / Broadband diffusion may enhance innovation, productivity, employment, economic growth, and, ultimately, national competitiveness. If key determinants for broadband diffusion are identified, governments can align its resources with them to effectively promote the diffusion. Based on the determinants of the diffusion rate identified by Rogers (2003) and Hall (2006), this research compiled data available about OECD countries as well as Taiwan to implement overall and staged panel regressions on fixed broadband diffusion by adopting Gompertz model. The findings indicate that the significance of the determinants varies between overall and staged analysis, which consequently justifies the necessity of a staged analysis. The key determinants in the early stage are income, education level, platform competition, population density, and the accumulated years of implementing LLU policy; however, in the late stage they are broadband price, Internet content, network effect, the penetration of dial-up users, and percentage of household with computer. Governments may more accurately promote broadband diffusion according to different key determinants in different stages.
This research further compared the real fixed broadband diffusion of Japan, South Korea, USA, Denmark, Switzerland, and Taiwan based on the previous analysis results. The findings generally justify the choice of key determinants in the previous analysis. In the early stage, Taiwan had the advantage of high population density. If the government could have promoted fixed broad banded services and market competition earlier, the penetration would have grown much faster. In the late stage, since the broadband price was too high in Taiwan, its international ranking of fixed broadband penetration declined. Therefore, in order to further promote the diffusion of fixed broadband, the government should have ensured that the price was low enough to convince the potential adoptors to purchase broadband services.
Finally, this research adopted the same approach as that of previous fixed broadband to analyze the diffusion of FTTX and mobile broadband, respectively. Education level, broadband price, network effect of FTTX, network effect of mobile broadband, Internet content, population density, percentage of household with computer, and the penetration of fixed VOIP users have significant effect on FTTX diffusion. However, income, broadband price, network effect of mobile broadband, Internet content, population density, and percentage of household with computer have significant effect on mobile broadband diffusion. Therefore, governments or operators should tailor their policies or strategies for specific services. The effects of broadband price, Internet content, network effect, and percentage of household with computer are similar in both FTTX and mobile broadband, and they are also similar to the key determinants of fixed broadband diffusion in the late stage. Therefore, even though a new service with better quality or function is introduced in an existing market, its key determinants are more similar to those of the existing service depending on its diffusion stage.
In conclusion, different from previous research, this one applied national-level data to quantatively analyzed and explore the key determinants of broadband diffusion based on innovation diffusion theory. The research findings not only propose policy and management suggestions to governments and service providers, but also supplement the the theory proposed by Rogers (2003) and Hall (2006), which did not identify and compare the determinants of innovation in different diffusion stages.
