本论文是以“ZG建材在线”这家网站公司为研究主体的案例报告。ZG建材在线是较早进行建材行业电子商务的网站，但其属性主要是一个第三方的信息发布平台，以会员形式收取相应的信息服务费为盈利手段。目前，在信息渠道越来越多样化以及电子商务越来越普及化的背景下，公司面临着会员增长空间有限、服务种类单一，并且盈利不足等问题。因此，论文根据建筑、建材行业的环境背景，以电子商务的发展趋势为指导，依托于现有的信息发布平台功能，提出拓展新的业务——建立第三方交易平台的发展思路。论文的重点是从建材行业发展电子商务的特点入手，找出建材买卖难以实现在线交易的原因，针对此项原因，结合ZG建材在线的自身情况以及市场需求，提出了开展第三方交易平台业务的基本思路，最后根据基本思路对交易平台的交易流程及重要功能进行了方案的设计。

This paper presents a case study report with “ZG Building Material Online”, a website company, as the subject. Although the website ZG Building Material Online is one of the early players conducting e-commerce in building material industry, it actually serves as a platform for the third parties to release information and thereby making profit by means of collecting corresponding service charges on membership basis. However, under the background of increasingly diversified information channels and popularized e-commerce businesses, the company is currently confronting with the following problems such as the limited possibility in membership expansion, the limited service options and the limited profitability etc.. Aiming at solving these problems, a new development strategy, namely, to develop new business by building the third party transaction platform, is put forward in the paper by considering the current situation of the construction and building material industries, following the development trend of e-commerce and relying on the functions of the existing information releasing platform. The essence of the paper is to start from the characteristics of the building materials industry developing e-commerce, and to identify the reason for why building materials trading is difficult to achieve online transactions. In allusion to this reason, as well as the company’s inner situation and the demands of the oriented markets, a basic guidance thought of how to develop the new business of the third party transaction platform is brought forward, which conducts the project design for the transaction workflow and the special functions.
