工商企业管理二班王建稳12292330051E-commerce is coming of ageThe 21st century are the information time, the tertiary industry unceasingly rise in the various countries' proportion, specially service industry, information service industry becomes for the 21stcentury the leading industries, this has caused the electronic commerce production and the development in the global information is under the influence which the situation drives, the various countries' electronic commerce unceasing improvement and the consummation, the electronic commerce is a focal point which each country and each big company capture. And, along with the whole world electronic commerce swift and violent development, the electronic commerce scale expands day by day, if US in 2000 the electronic commerce amounts to 488.7 billion US dollars, Japanese 31.9 billion US dollars, German 20.6 billion US dollars. Thereupon, the various countries unceasingly opens sends out the form to be diverse, the characteristic each different electronic commerce solution. But, because various countries and some international organization to electronic commerce understanding existence difference, thus the formulation and implementation development electronic commerce policy also has the obvious difference between the country and the country electronic commerce live agent lacks the effective coordinated mechanism to develop slowly, simultaneously a country interior electronic commerce activity also because of lacks the effective policy safeguard to receive the restriction. Therefore, the research discussion electronic commerce present situation and the formulation implementation appropriate electronic commerce policy question extremely is urgent. But in our country, the computer and the network technology popularization and the development, the electronic commerce rapidly rises, the multitudinous information technology enterprise, the venture capital company, the production circulation enterprise develops the electronic commerce in abundance. Looked from national Economical trade committee to more than 630 enterprises' investigations that, at present enterprise in Internet application and development electronic commerce aspect, eastern area enterprise good to middle area, middle is markets. But many record shops and travel agents could be in for a tougher time. Erik Blachford, the head of IAC’s travel side and boss of Expedia, the biggest internet travel agent, thinks online travel bookings in America could quickly move from 20% of the market to more than half. Mr Bezos reckons online retailers might capture 10-15% of retail sales over the next decade. That would represent a massive shift in spending. How will traditional shops respond? Michael Dell, the founder of Dell, which leads the personal-computer market by selling direct to the customer, has long thought many shops will turn into showrooms. There are already signs of change on the high street. The latest Apple and Sony stores are designed to display products, in the full expectation that many people will buy online. To some extent, the online and offline worlds may merge. Multi-channel selling could involve a combination of traditional shops, a printed catalogue, a home-shopping channel on TV, a phone-in order service and an e-commerce-enabled website. But often it is likely to be the website where customers will be encouraged to place their orders. One of the biggest commercial advantages of the internet is a lowering of transaction costs, which usually translates directly into lower prices for the consumer. So, if the lowest prices can be found on the internet and people like the service they get, why would they buy anywhere else?One reason may be convenience; another, concern about fraud, which poses the biggest threat to online trade. But as long as the internet continues to deliver price and product information quickly, cheaply and securely, e-commerce will continue to grow. Increasingly, companies will have to assume that customers will know exactly where to look for the best buy. This market has the potential to become as perfect as it gets. Certain products or services appear more suitable for online sales; others remain more suitable for offline sales. While credit cards are currently the most popular means of paying for online goods and services, alternative online payments will account for 26% of e-commerce volume by 2009 according to Celent. Many successful purely virtual companies deal with digital products, (including information storage, retrieval, and modification), music, movies, office supplies, education, communication, software, photography, and financial transactions. Examples of this type of company include: Google, eBay and Paypal. Other successful marketers such as use Drop shipping or Affiliate marketing techniques to facilitate transactions of tangible goods without maintaining real inventory. Examplesinclude numerous sellers on eBay. Virtual marketers can sell some non-digital products and services successfully. Such products generally have a high value-to-weight ratio, they may involve embarrassing purchases, they may typically go to people in remote locations, and they may have shut-ins as their typical purchasers. Items which can fit through a standard letterbox — such as music CDs, DVDs and books —are particularly suitable for a virtual marketer, and indeed , one of the few enduring dot-com companies, has historically concentrated on this field. Products such as spare parts, both for consumer items like washing machines and for industrial equipment like centrifugal pumps, also seem good candidates for selling online. Retailers often need to order spare parts specially, since they typically do not stock them at consumer outlets -- in such cases, e-commerce solutions in spares do not compete with retail stores, only with other ordering systems. A factor for success in this niche can consist of providing customers with exact, reliable information about which part number their particular version of a product needs, for example by providing parts lists keyed by serial number. Purchases of pornography and of other sex-related products and services fulfill the requirements of both virtuality (or if non-virtual, generally high-value) and potential embarrassment; unsurprisingly, provision of such services has become the most profitable segment of e-commerce. There are also many disadvantages of e-commerce. one of the main ones is fraud. This is where your details (name, bank card number, age, national insurance number) are entered into what look to be a safe site but really it is not. These details can then be used to steal money from you and can be used to buy things on line that you are completely unaware of until it is too late. this information is leaked into the wrong hands. People are able to steal your identity, and commit more fraud crimes under your name. Finally there are many problems with e commerce some of which are: Failure understands customers why they buy and how they buy. Even a product with a sound value proposition can fail if producers and retailers do not understand customer habits, expectations, and motivations. E-commerce could potentially mitigate this potential problem with proactive and focused marketing research, just as traditional retailers may do. Failure consider the competitive situation. One may have the will to construct a viable book e-tailing business model, but lack the capability to compete with Amazon. Inability predicts environmental reaction. What willcompetitors do? Will they introduce competitive brands or competitive web sites? Will they supplement their service offerings? Will they try to sabotage a competitor's site? Will price warsbreak out? What will the government do? Research into competitors, industries and markets may mitigate some consequences here, just as in non-electronic commerce. Over-estimation of resource competence. Can staff, hardware, software, and processes handle the proposed strategy? Have e-tales failed to develop employee and management skills? These issues may call for thorough resource planning and employee training. Products less suitable for e-commerce include products that have a low value-to-weight ratio, products that have a smell, taste, or touch component, products that need trial fittings —most notably clothing —and products where color integrity appears important. Nonetheless, has had success delivering groceries in the UK, albeit that many of its goods are of a generic quality, and clothing sold through the internet is big business in the U.S. Also, the recycling program Cheapcycle sells goods over the internet, but avoids the low value-to-weight ratio problem by creating different groups for various regions, so that shipping costs remain low.译文：电子商务是时代的到来21世纪是信息时代，第三产业不断上升，在各国的比重，特别是服务业，信息服务业成为，21世纪的主导产业，这导致了电子商务的产生和发展，在全球信息该驱动器的情况的影响下，各国的电子商务不断的改进和完善，电子商务是每一个国家和每一个大公司捕捉的焦点。
