中国为什么没有率先创建经济学

科学、包括经济学的创建由人类的需要决定。自利经济人假设和资源稀缺性假设既是经济学的两个基本假设前提,也是决定经济学产生的根本因素,当人数量足够多而且个体需求和欲望足够大时,资源稀缺度自然也足够高,于是经济学就会产生;西方大航海时代的地理大发现推动了贸易全球化、市场经济和工业革命,既促进了人口增长又极大地刺激了人的需求和欲望,从而加剧了资源稀缺性,于是经济学率先在西方产生和发展。而同时代中国,政府或王公贵族们依靠集权和苛捐杂税剥削众多不知道信息、没有多大欲望的老百姓,就有取之不尽用之不竭的财富,所以没有足够的内在动力开拓世界市场、获取财富,在对世界认知严重偏误情况下自足、自满、自大,盲目陶醉于世界大国和强国的幻想中,因此,既没有内在动力、又没有外在的国家之间的竞争压力去开启科学意义上和经济意义上的航海时代和地理大发现,因此不可能与西方同时产生经济学。没有很强烈的需要或必要创建经济科学,也许还与彼时中国没有先进教育理念指导下训练出来的科学思维有关,当它后来有必要创建经济科学的时候(人口众多并且欲望强烈的时候),经济科学已经产生并且理论体系趋于成熟。应该充分肯定中国经济学家们对经济学发展作出的贡献,对创建经济学的中国学派还需要进一步的思考。

城市经济学文献综述研究——基于城市经济学研究的基本问题的视角

城市经济学是一门研究城市地域范围内的资源优化配置问题的学科,属于空间经济学的范畴。城市经济学作为一门独立的学科存在,自然有其独特于其他学科的一些研究范式。首先它属于经济学的研究范畴,那就避免不了研究城市中的经济学问题,这就回到了通常的经济研究领域,也就是研究城市中如何实现资源的有效配置,研究城市经济如何实现可持续增长。其独特之处就在于它把经济的研究放在了城市这一特定的空间之上。我们自然就会问:什么是城市?城市是怎样形成的?城市经济又是怎么样发展的?城市的边界在哪里?城市空间下的城市问题有哪些?这些正是这一学科的重点或者叫研究对象。

Comparative Utilization of Different Fibre Feedstuffs by Weaning/Growing Pigs in the Tropics

This study was conducted to investigate the effect of feeding different fibre feedstuffs on the performance, nutrient utilization and economics of production of weaning/growing pigs. Five fibre feedstuffs--palm kernel cake （PKC）, wheat offal （WO）, corn bran （CB）, rice bran （RB） and brewers＇ dried grain （BDG） were used at 25% in each of the five experimental diets that were formulated in this study. Twenty weaner pigs （12.75 ± 0.6 kg） were used for the growth study while 15 pigs （14.95 ± 0.57 kg） were used for the digestibility study. The design of the experiment was completely randomized. The results of the study showed that the performance of the experimental animals were significantly influenced （P 〈 0.05） by the dietary treatments. The apparent digestibility of the crude protein, crude fiber and ether extract showed significant differences （P 〈 0.05） while there was no significant difference （P 〉 0.05） in the apparent digestibility of their dry matter, ash and nitrogen free extract. The diet that contained WO had the best growth response and apparent nutrient digestibility. Results of economics of production also showed that diet with WO gave the best （P 〈 0.05） value in feed cost/＇kg gain and net profit/animal. It can be concluded from this study that although all the animals fed the different fibre feedstuffs performed satisfactorily on all the parameters monitored, but for optimum growth, apparent nutrients digestibility and economics of production. WO should be used as a fibre feedstuff in the diets of weaning/growing pigs in the tropics.

LOCATION AND ECONOMIC GROWTH:CASE STUDY IN CHINA

This paper explores how location could affect economic growth and it has always been omitted in economic analysis. Geographic factors can affect economic activities. Three mechanisms of location affecting economic growth have been studied: consumption, production and migration. The initial superior location will take such advantages as lower transport costs and lower price level, so it could have higher consumption utility, higher productivity, and attract more human capital, then lead higher growth. Those regions with the superior location will have higher utility due to more product varities and the comparative lower price, and higher wage due to the production technology, and it would attract more individuals with higher human capital to move to this location. It is a kind of agglomeration, meaning the superior location will hold more advantages and higher growth rate, otherwise those locations with poor geographic factor will be even worse. Based on Chinese provincial economic growth experiences of these years, this paper does some empirical analysis by regressing on some variables including the geographic ones. In this paper, the dummy variables and population density are used to measure the location factor. And we find evidences supporting the view that dominant locations such as coastal areas grow faster, on the contrary,middle and western provinces grow slower. Location does affect economic growth.

The Impact of Handicrafts on the Promotion of Cultural and Economic Development for Students of Art Education in Higher Education

This paper studies the impact of handicrafts on the promotion of cultural and economic development for students of art education in higher education through handicrafts based on local customs and traditions. Descriptive, analytical, and experimental methods are used in this research. The results of the study are expected to benefit from the results of this study to provide planners handicrafts in the Ministry of Education. An effective strategy can affect the teaching and learning of handicrafts, the protection of its features and its presence and identity. The study sample consists of 45 students of the third level, batch 2012-2013, from the faculty of Education at the University of Khartoum, Republic of the Sudan. The researchers to prepare topics for handicrafts depend on the use of local materials and units which are derived from the environment and represent the Artistic heritage that is shown through handicrafts （pottery, ceramics, calligraphy, decoration, carpet weaving and textile, sewing, embroidery, sculpture and engraving on wood, metal works, and printing works）. The researchers focuse that the students learn the value of handicrafts in terms of economic and method of production and take advantage of it to increase the income of the individual product. The results confLrms the existence of a difference in the quality and value of handicrafts for students in both groups： the experimental and control group, which confirms that the handcrafts lead to the promotion of cultural and economic development for students of art education in higher education. The researchers are recommended to consider of this topic as a main component which enables an area for further studies to develop different strategies in the field of handicrafts, for students to recognize the importance of the handicrafts value in terms of economic and method of production and take advantage of it to increase the income of the individual product.

Characteristics, Constraints and Perspectives of the Fish Farming in Burundi

The fish farming was introduced in Burundi in about 1950s. Actually, several fish ponds were abandoned and many others were still unproductive. This study aims to present current state and perspectives of the fish farming for its real contribution to the socio-economic development. The results presented are compilation of physical and chemical parameters series measured in fish ponds and inquiries led in 2010-2014 to the fish farmers in seven provinces （40% of the total area of the country）. Weak values of some physical and chemical parameters showed that the majority of ponds are badly maintained. Thus, the dissolved oxygen values varied between 0.2 mg/L and 3.5 mg/L. The high relinquishment rate of the fish fanning （between 40% and 67% according to the provinces） could be explained by many constraints： no centers of fish farming breeding for various fish species and no production center of complete foods with local sub-products. About 75% of fish famers confirmed that they have never benefited framing in fish fanning. In spite of the diverse constraints, Burundi has a dense rivers system with favorable physical and chemical parameters and many appropriate sites for the fish farming. Thus, the main suggestions concern the sector reorganization.

Intellectual Property Rights on Plant Genetic Resources:Perspective from Economics

Given the existence of transaction costs,the location of property rights is an important factor in determining the incentives for efficient levels of investment at various levels of the industry.This paper applies some of the economic theories of property rights and industrial structure to the issues concerning the conservation of biodiversity.Although the expansion of Intellectual Property Rights (IPR) systems into the area of genetic resources has increased private investment in R&D process of the agriculture,it does not generate enough incentives for in situ conservation of biodiversity.To solve this economic inefficiency,farmers'rights and other design of incentives and institutional arrangement should be reconsidered.

Growth Performance, Feed Conversion Ratio and Economics of Production of Native and Crossbred （Local x Holstein Friesian） Bulls for Fattening under Different Improved Feeding

An experiment was conducted to evaluate the growth performance and cost per gain of indigenous and crossbred （local x Holstein Friesian （L x HF）） bulls under four different improved feed treatments to determine the appropriate ration for economic organic beef production in Bangladesh. Twenty indigenous bulls （average body weight 208.08 ± 13.98 kg） and 20 crossbred （L x l-IF） bulls （average body weight 256.26 ± 26.85 kg） of 24 months age were divided into four equal groups and fed on four diets （T0, T1, T2 and T3） up to 120 d, where To referred to the conventional diet, and T1, T2 and T3 referred as improved organic diets. Required dry matter for individual animal was supplied by roughage and concentrate sources of the ration in the ratio of 2：1. Local grass and paddy straw were supplied to group T0 and T1, Napier grass and straw to group T2, and Napier grass （Pennisetum purpureum）, straw and Ipil-ipil leaf （Leuceana leucucephala） to group Ts as roughage; whereas, the concentrate was supplied as 1.5% of live weight. The results revealed that total dry matter intake （DMI）, total DMI as percent live weight （%LW）, feed conversion ratio （FCR） and average daily gain （ADG） varied significantly （P 〈 0.01） among different treatment groups. Breed also had significant （P 〈 0.01） effect on total DMI, FCR and ADG, but total DMI （%LW） was not affected by breed type. Feed cost expressed as per kg live weight gain （LWG） （BDT/kg LWG; 1USD = 78.95 BDT）, were also affected （P 〈 0.01） by feed treatments and breed type. Indigenous and crossbred bulls fed diet T3 had higher ADG （0.49 kg and 1.17 kg, respectively） and comparatively lower feed costs （156 BDT/kg LWG and 96.78 BDT/kg LWG, respectively）. But crossbred （L × HF） bulls showed the highest ADG （1.17 kg） and the lowest feed cost （96.78 BDT/kg LWG）. Therefore, considering the growth performance and cost per kg gain of the experimental animals, it may be concluded that the crossbred （Lx HF） bulls treated with T3 diet may be used for economic organic beef production in Bangladesh.

A Strategy to Strengthen the US Economy

For decades, the United States＇ competitive position in global manufacturing has steadily declined. Analysts point to increasingly automated manufacturing processes, changing domestic demand factors, outsourcing, and over confidence in service export surplnses. However, Asian and European competitors, undergoing the same pressures, have been able to maintain a healthy percentage of their GDP in manufacturing by growing high techjobs while the United States continues to fall behind, Perhaps the most flmdamental and overlooked contribution to this decline is the lackluster performance of the United States education system. After comparing the performance of US students to that of the other G-8 nations in the critical disciplines of math and science literacy, US students rank last. Furthermore, the most recent PISA test results show US students rank in the bottom half of 30 participating nations in the ability to apply math and science concepts to real world problems. This is particularly troubling when one considers that among the compared nations, the US spends the most on math and science teacher compensation. If the US intends to successfully compete in the global manufacturing arena, significant changes to the education system must be enacted. A new strategy aligning the system with real world demands should begin with a national initiative to increase Pre-K enrollments, a paradigm shift from liberal arts to math, science, problem solving and critical thinking, standardized policies aligning high school graduation requirements with college and work place expectations, and standardized college and career readiness assessment programs. These steps combined with more rigorous secondary education teacher certifications, continued education and involvement with universities and manufacturing f＇mns within the community, should more adeq^tely prepare high school students for further study or to enter the skilled workforce. At the post secondary level, federal and state funding should be targeted to R＆D programs specificly to industrial design, engineering, and alternative energy. Industry investment in such programs should be federally incentivized to foster cooperative relationships between business and academia. Such relationships will ensure faculty spend time focusing on how their discipline relates to manufacturing and instilling the necessary skill sets, knowledge and abilities which graduates will need to compete in the global market. Such a revised system will position the US to create and keep high paying manufacturing positions on its way to sustainable economic growth.
