Long-term Dynamics of Cultivated Land Resources and Their Driving Forces of Guyuan City in Upper Reaches of Jinghe River

The land use patterns in Guyuan City,Ningxia Hui Autonomous Region of China,have changed greatly over the years,due to population growth and farming and stock raising development.This study,using 50-year statis-tical data of cultivated land and 14-year spatial data of land use pattern,analyzed the developmental stages,the char-acter,and the spatial variance of farmland in the city,and discussed the driving forces of cultivated land changes based on empirical and conceptual statistical models.First,the change of cultivated land area went through different stages of rapid increase,fluctuating change,decrease and rapid decrease from 1949 to 2004,additionally,social and economic policies in different stages had an important impact on farmland variance.Second,from 1986 to 2000,the quantity of cultivated land increased,but its quality decreased.Third,social and economic factors are determinant factors in culti-vated land transition.Five constructed paths explain cultivated land transition.Factors that have direct or indirect ef-fects on farmland include the economy(Xeco),the population(Xpop),agricultural output(Xagr),and scientific input(Xsci).The sequence of impact was Xeco>Xpop>Xsci>Xagr.Among all these impacts,Xeco was the major positive one,and Xpop was the major negative one.It is urgent to take measures or adopt a policy to stop the vicious cycle in eco-environment and agriculture production.Otherwise,negative patterns of farmland use will increase,and high-quality cultivated land will continue to decline.

The study of the life cycle of technology assessment model

The life cycle of technology is one of the most important indexes to weigh up the risk of the investment to neo tech.There are so many uncertainties because it is conditioned by a lot of factors,we can not make a rational forecasting by traditional assessment method.So this paper gives a comprehensive consideration to the factors that influence production and makes some modification to production function, and establishes the life cycle of technology assessmet model by the method of fuzzy mathematics. So it quantifies the risk of investment.We can take it as one foundational index for the decision making of the investment.

Optimization of Equipment Maintenance Strategy Based on Availability

It is very important to optimize maintenance strategy in maintenance plan. Proper parameters play a decisive role for the optimization. In the opinion of writer, availability is a basic parameter, failure consequence cost and failure characteristic are also important parameters.

Scheme for Implementation of an Economic 1→3 Quantum Cloning Machine via Cavity-Assisted Atomic Collisions in Cavity-QED

A scheme to implement of 1 →3 economic phase-covariant cloning machine for unknown equator state in cavity-QED is proposed. The scheme requires cavity-assisted collision processes between atoms, which cross through nonresonant cavity fields in the vacuum states. The cavity fields are only virtually excited so that the cavity quality factor can be loosened.

Letter from Editors-in-Chief

Engineering comes to you at last. As the Editors-in-Chief of En- gineering, first of all, we wish to thank all the scholars at home and abroad for their eager responses and full support, and all those who have provided encouragement and contributions toward the emergence of this journal. Looking back over the history of human civilization, hu- man survival is closely related to the development of social productive forces, which come from engineering science and technology （EST）. Along with today＇s rapid economic and social development, we face common threats from global problems such as food safety, resource shortages, energy cri- ses, environmental pollution, climate change, network attacks, population expansion, poverty, the prevalence of disease, and economic crises. Therefore, EST research that addresses these major issues of economic development appears to be par- ticularly important. At present, a new scientific and technical revolution, including wide spread industrial transformation, is flowing together with new developments in human society. Historically, we know that progress and innovation in EST is a crucial engine for promotin~ progress in human society.

Technology in New Institutional Economics --Comparison of Transaction Costs in Schumpeter＇s Capitalist Development Ideology

In mainstream economics （the neoclassical economics）, it is accepted that every company that competes under the perfect competition market has the same technological equipment. So, technology is approached as a simple efficiency increase whose source is unknown. In terms of established economics view, technology is like a ＂black box＂ that cannot be predicted. As the creator of the concept of＂creative destruction＂, Joseph Schumpeter （1883-1950） caused significant changes in terms of the view of neoclassical economics about technology. On one hand, Schumpeter created a new point of view about the concept of＂innovation＂ by using key concepts, such as ＂invention＂, ＂imitation＂, and ＂business cycles＂. Schumpeter＇s ＂creative destruction＂ concept carries out the role of a new map for the new institutional economics trend which accepts ＂technology＂ as an institution. On the other hand, if one is to understand why the ideology differs between neoclassical economics and new institutional economics, ＂transaction costs＂ should be analyzed. Since, transaction costs and creative destruction have a relationship between each other; Schumpeter and Coase＇s ideas are resembling each other. While doing this, this paper will try to discuss the question of how to accept the technology as ＂external＂ instead of ＂internal＂ limit neoclassical economics. In this process, it will primarily base the dimension on the concept of＂technology＂ developed by Schumpeter. The second station is an inquiry between Schumpeter＇s and Coase＇s ideas about technology. Although new institutional economics （NIE） and neoclassical economics can be confused, they can be seperated from each other by the way they look at technology. Because, technology is accepted as an external theme by neoclassical economics, on the contrary, NIE acceptes technology as an internal fact. One of the most important reasons why technology is internal in terms of NIE can be evaluated by ＂transaction costs＂. As a result, the author will give effort to create a critical presentation in order to readdress the viewpoint of mainstream economics about ＂technology＂.

Biotechnology Development Status and Prospects

More and more people have foreseen the arrival of a new era of life sciences, which has important impact on science and technology development, social progress and economic growth.

Theoretical research and practical application of Mathematical economic models

Mathematical economic modeling is widely used to provide a reference for policy makers and guidance for the specific work of many departments, such as saving expenditures, reducing costs and improving profit. Particularly, it can predict and estimate the future, playing a great role in promoting the rapid development of science and technology as well as the management of market economy. In general, mathematics does not directly deal with the objective conditions on the management of market economy. In order to use mathematics to solve problems in the field of the management of market economic, it is necessary to carry out mathematical economic modeling.

Prospects Analysis Regarding Integration of the O&G Industry with Internet from an Economics Perspective

Along with worldwide Internet boom, China's Internet industry is also thriving and has achieved remarkable success. Beyond that, industry integration between the Internet and other fields, such as finance, retail and advertising, is also eye-taking, as it has fostered a novel industry chain structure and business model. With an aim to realize the transformation and upgrading of conventional industry, the Chinese government has proposed ‘Internet plus' to encourage the combination of the Internet and conventional sectors. As one of the most important and complex conventional industries, the oil and gas(O&G in abbreviation) industry is also seeking the opportunity to actively cooperate with the Internet. However, after analysis of the differences between the particularities of the O&G and Internet industry from an economics perspective, a comprehensive combination of these two seems less promising, but adopting Internet related technologies to improve the performance of the O&G industry is feasible.
