According to the China Construction Machinery Industry Association statistics show that by the end of 2011, China's construction machinery main products of more than 5.4 million units, the current forecast, 2012 reached 57-5.9 million units, 2013 reached 62-6.35 million units. Such a huge number of units combined with the reduction of the amount of infrastructure construction machinery industry from May 2011 began to cool down rapidly and gradually entered the trough period, whether it is the sales of products or the operating rate of the project have shown a weak state, so far there is no obvious sign of improvement.

　　How can industry customers achieve a more reasonable return on investment and reduce risks under the current situation? After a series of investigation and analysis, it is concluded that second-hand equipment will become a new way of survival and profit in the construction machinery industry. In the past two years, many people have turned their attention to second-hand equipment, buying second-hand equipment at low prices compared to new machines. As we all know, second-hand construction machinery investment has the characteristics of less investment and fast income, which not only reduces the investment cost of equipment for enterprises and individuals, but also fully meets the needs of engineering construction to a certain extent. Therefore, buying used equipment for small and medium enterprises and individual contractors is a good way to invest.

　　At present, the domestic second-hand construction machinery and equipment are mainly dealt with by personal transactions, second mobile phone trading markets, manufacturers and agents with a reserve price and no reserve price auction. However, the tide of mobile Internet has come and brought new opportunities. My team and I have paid close attention to mobile Internet in the past two years, and made various explorations and attempts in this field. After a year of research, preparation and planning, Our construction machinery O2O project second-hand exchange second-hand construction machinery trading network was officially incubated, to provide you with a more relaxed, more convenient, fair and just online bidding purchase way.

　　Currently, there are three mainstream O2O models:

　　The first type: online drainage for the offline, through the online traffic, to bring customers to the offline merchants, the online platform to earn commission;

　　The second category: online and offline sales channels parallel, this model requires enterprises to have their own stores or agents, which brings pressure to offline stores and agents, so manufacturers generally try to maintain the same price online and offline.

　　The third type: offline for online flow, this model is similar to Suning, offline experience, online transaction model.

　　Due to the particularity of the construction machinery industry, the current construction machinery industry O2O new media still uses the first model.
