Development mode of the E-commerce of eco-agriculture products in China

With the extensive use of the Internet and mobile technology, E-commerce in China has shown tremendous growth advantages and market potential, especially in promoting the access of eco-agriculture products. The E-commerce of agriculture products has shown diversification on the mainstay. "Three products, one indication"(pollution-free, green product, organic product, geographical indication) has becomes the primary character. Although the market of fresh products occupies a limited and meager profit, the blue sea effect has caused capital to enter into a large-scale development. It is very clearly shown after the analysis that the market of eco-agricultural E-commerce is vast and the expansionist policy for E-commerce environment is favorable. Meanwhile the required hardware and software of network in E-commerce are basically equipped with rapid development of service technology and strong driving force for innovation and development as well as an endless stream of new models and platforms. The whole phrase of development can be divided into five major stages. Through the analysis of five perspectives, such as platform, driver, participant, food supplier and Taobao, 16 types of agro-products E-commerce models and their different types of e-payment support systems are summarized, revealing the two major bottlenecks of development, namely the markets with limited share and low profit-making and the impact of cold chain services on E-commerce development. The thesis finally fortells the ten trends for the future development.

Analyzing Collaborative Development of E-Commerce and Logistics Based on DEA

In order to know the current collaborative development situation and relationship of E-commerce and logistics, the paper evaluates the whole collaborative development level of Chinese E-commerce and logistics from 2008 to 2014 using the DEA model. Fund, infrastructure, labor and collaborative development are evaluated and analyzed in this model. The research indicates that E-commerce facilitates the logistics development but logistics can’t support E-commerce development well due to the lag effect which leads to lower collaborative development level. So optimizing the ratio of logistics investment and output, promoting logistics service quality and accelerating logistics development have been the key factors for promoting the collaborative development of E-commerce and logistics.

High speed railway promoting development of low-carbon economy in China

Low-carbon Economy is a kind of economic developing mode which takes low energy consumption,low pollution and low discharge as its foundation. It is another important revolution of the human society after the agriculture civilization and industry civilization. It deals with various fields including low-carbon energy,low-carbon agriculture,low-carbon industry,low-carbon transportation and low-carbon life,etc. Among those,low-carbon transportation is one of the important contents. Since high speed railway uses electricity as driving force,it runs without discharging waste gas,and it is a kind of clean and green transportation with little dust and smoke black. Therefore,the study of the relationship between the high speed railway and low-carbon economy is becoming one of the important frontier problems that confronting the theoretic circle. With demonstration analysis and comparative analysis,this paper discusses the comparative advantages of high speed railway in terms of energy saving and environment protection,treatment of sound pollution,land saving and reduction of external cost(mainly pollution treatment cost) ,etc. compared with the other transportation modes and ordinary railway. Taking Beijing-Tianjin Intercity Railway as an example,the paper further demonstrates the distinctive advantages in respect of energy conservation and emission reduction. Besides,the paper also predicates the low-carbon effects after several high speed railways is put into operation in a few years. It is concluded that the development of high speed railways will meet the need of low-carbon economy and is significant for sustainable and steady development of economy and society.

Evaluation of Early High Speed Development of Bottom Water Heavy Oil Reservoir

The bottom water heavy oil reservoir has high natural energy, and the bottom water body multiple of the reservoir is 300 times or even higher. The natural energy of the reservoir can keep the superior condition that the formation energy does not decrease under the condition of large liquid volume and high recovery rate. In view of this reservoir condition, we take C oilfield as an example to carry out the oilfield development effect under the condition of large liquid volume and high-speed production, and analyze the influence of high-speed production and medium low-speed production on recovery rate of similar heavy oil bottom water-reservoir. The results show that the rising trend of water cut in oilfield is the same whether high-speed development with large liquid volume or conventional low-speed development is adopted. Under the condition of high liquid production, the sweep efficiency of water flooding is high in the same period of time, which has certain advantages of enhanced oil recovery. The development mode of early large liquid production is explored, which provides certain guidance for the efficient development of heavy oil reservoir with bottom water.

Some Critical Issues in the Development of Chinese High-Speed Rail: Challenges and Coping Strategies

In this paper, several critical issues related to Chinese high-speed rails (CHSR) are analyzed, investigated and discussed, including development background, reasons for high ticket fare, some typical factors that influence the environmental life-cycle assessment, time and cost comparison of typical door-to-door travel routes between different transport modes and complementary strategies among different transport modes. First, the results show that the expanding high-speed rail network increased the pressure on the country's roads in the 2010 spring festival rush period due to the high ticket fare of CHSR. Second, due to lower than expected ridership because of the high ticket price and limited demand in less developed areas, some Chinese CHSR projects have become economically unsustainable. Third, without sufficient ridership and service life, the utilization of HSR was unable to show any advantages in the environmental impact compared with the other transport modes. In addition, the impact of shock from CHSR on Chinese domestic civil airlines is evident when the travel distance is below 1050 km. The key objective of the investigation is to enhance our understanding of the development and operation of Chinese high-speed rail. One of the key contributions of the current paper is the presented suggestions for complementary strategies between different transport modes to make full use of Chinese transportation resources to promote low carbon economy.
