本篇論文主要在探討台灣行動電子產品的市場擴散模式，以行動電話、筆記型電腦與PDA為例，來探討個別行動電子產品的產業發展概況。 ■　行動電子產品的擴散模式，有以下的特性： 1. 在運用技術採用生命週期理論前，需要先注意本身產品的特性，如「易攜性與方便使用」、「具個人隨身資訊管理功能」、「具傳輸資料的通訊功能」、「具智慧型處理能力」，以瞭解會吸引何種潛在使用者。 2. 行動電子產品本身的可攜性、資料處理功能，皆吸引了第一區隔族群的早期使用者購買，因此行動電子產品的初期銷售皆呈現了一波看好。 3. 行動電子產品面臨的成長不連續，是由於產品本身的功能性已吸引第一區隔族群的早期使用者，因此可呈現一波成長。但因為產品的「可靠性」、「便利性」以及「價格」因素的問題，無法吸引早期大眾的青睞，讓產品本身的市場發展出現不連續的狀態。 4. 行動電話、筆記型電腦、PDA等，其在產品的功能性上皆可吸引早期使用者的購買，但在吸引早期大眾的購買上，還是以改良其操作介面、提高產品的穩定度來做著手。因此真正影響到潛在使用者購買產品的，決定性因素還是在於產品本身的特性，若產品的價格功能比達到潛在顧客的標準，以及其操作便利性容易，則會吸引潛在顧客的購買。外部環境的影響以及資訊擴散對於提升潛在使用者購買動機的影響較小，而是以將非潛在使用者進而轉變成為潛在使用者較有所幫助。而除了外部環境與資訊擴散外，產品本身功能的延伸也可以擴展潛在使用者的數量與族群。 5. 行動電子產品的主要兩個區隔族群：「商業人士」、「非商業人士」，早期使用者主要存在於商業人士中，而非商業人士則是以早期大眾、晚期大眾為主，因此要提升產品的銷售，可由鴻溝出現前的顧客需求與非商業人士的需求差異，作一比較，針對其中的產品特性差別作改善。 ■ 資料處理取向的筆記型電腦與通訊導向的行動電話在族群擴散時，不同點為： 1. 資料處理取向的筆記型電腦與PDA，由於其潛在顧客數量與族群本身就被資料處理、數位助理限制住，因此容易讓潛在顧客陷入成長的困境中。因此若要讓潛在顧客群的數量有大量的提升，則需要靠電腦教育的普及，以及網際網路的助益，才有辦法讓電腦使用人口提升，進而增加潛在使用者的數量。 2. 相較於通訊導向的行動電話，由於行動電話本身的通訊功能是大眾不可或缺的，因此其潛在顧客群規模本就比較大，發展的潛力也大了很多。 3. 除了潛在使用者的問題，筆記型電腦與行動電話本身的使用障礙也有很大的差異，筆記型電腦本身的視窗系統雖然越來越人性化，但其問題與安裝仍有進入障礙，不像行動電話的軟體系統上使用便利，因此其成長曲線呈現快速的成長。 4. 在資料處理與通訊功能結合下，將會產生無線數據傳輸的功能，而在這兩功能的族群交集下，由於於資料處理的族群數量有限，因此其潛在使用者可能不是無線通訊的使用者，而較可能為是同時使用兩種功能下的使用者，因此可考慮在此前提下進行族群的探討與發展。 / Since 1997, the mobile electronic products became more and more popular, including mobile phone, notebook computer, and PDA. Because of the revising of communication law in 1997, the wartime of the mobile phone industry came. More and more people in Taiwan started to pay attention to mobile phone, and cheaper and cheaper the price of mobile phone is. In this way, the mobile market in Taiwan grows very fast. The rate of popularity of mobile grew to 80+% in 2000. Since the price of notebook computer down in 1997, the sales of notebook became better. Beside the price down, the popular of Internet and Win95 system are the main reason of the growth of notebook market. Another mobile electronic product: PDA, will be the next star of mobile electronic product. That is why this thesis trys to discuess these three mobile electronic products. <Objectives> This thesis trys to investigate the growth of the market of mobile electronic product, including mobile phone, notebook computer and PDA. This thesis will discuss the diffusion model of mobile electronic product in Taiwan, including the diffusion of distinguish of customers, the model of each different product the same or not. The furthermore, this thesis still try to establish the common diffusion model of mobile electronic product. The main object of this thesis is: 1. The characteristic of mobile electronic product. 2. The develop model of each mobile electronic product market before the growth of discontinuity. 3. The reason of the discontinuous growth of each mobile electronic product. 4. The influence of product reformation, diffusion channels and environment on the diffusion of divisive customers. 5. To develop the common diffusion model of mobile electronic product by the characteristic. <Research Structure> This thesis is based on diffusion of innovation as the core and supported by the industry report. According the diffusion reports and book, a diffusion model should include four elements—environment, product characteristic, diffusion channel and divisive customers. The research structure is as follows: In this diffusion model, including four main elements—environment, product characteristic, diffusion channel and divisive customers, each one element effect on another one. The environment would affect the characteristic of product and diffusion channel and customer behavior. The characterisic of product will affect on the customer’s purchase desire. The diffusion channel will decide how many customers knowing the product, and the diffusion channel include two kinds of channel—production diffusion and information diffusion. <Case Choice> This thesis choose three mobile electionic product: 1. mobile phone 2. notebook computer 3. PDA <Research Methodology> This theris adopts the case study using industry report and in-depth managers and customers interviews. Before interviewing, the author has collected related data and the under-practicing data of every industry. <Case Analysis and Conclusions> 1. Before using ‘Technology Adoption Life Cycle’, we have to understand the characteristic of the mobile electronic product, in order to understand what kind of customer will be attracted. 2. The property of carrying and data processing of mobile electronic product will attract the early adopters of first division customers. 3. The discontinuous growth of the product is because of the incomplete of reliability, convenience and price, so the early majority don’t want to purchase the product. 4. To make the customer to purchase the product, the critical factor is the characteristic of the product. If the product has complete capability, the customers will have willing to buy. 5. The main two divisive customers is ‘business people’ and ‘not business people’. The most of the early adopters is included in first division, and the second division is mainly formed of early majority and later majority. If we want to know the difference between the demand of early adopters and early majoritys, we can know it by comparing the demand of first division with second division.
