Rice is the most important and extravagant food in Burundian consumption for no more than 5 kg on average per people by year. It＇s especially suitable to plant rice in Burundi because of the sufficient sunlight and rain. But the lack of new varieties, practical technology and modern service make it very difficult for rice production. According to this significant roll, the rice production has to be increased in order to satisfy the consumption needs which are now becoming higher and keep the food safe. This article mainly shows the rice ecological types, production facts and the major constraints of rice production in Burundi, and then look into the distance on how to solve the problems.展开更多

However, after the policy of reform and open-up was taken in China. the economic development speed and efficiency ofthis area have turned to be evidently lower than those of coastal area and the national average level as well, which is so-called ＇Northeast Phenomenon＇ and ＇Neo-Northeast Phenomenon＇. In terms of those phenomena, this paper firstly reviews the spatial and temporal features of the regional evolution of this area so as to unveil the profound forming causes of ＇Northeast Phenomena＇ and ＇Neo-Northeast Phenomena＇. And then the paper makes a further exploration into the status quo of this region and its forming causes by analyzing its economy gross, industrial structure, product structure, regional eco-categories, etc. At the end of the paper, the authors put forward the basic coordinated development strategies for Northeast China. namely we can revitalize this area by means of adjustment of economic structure, regional coordination, planning urban and rural areas as a whole, institutional innovation, etc.展开更多

On the basis of an analysis of the evolution processes and characteristics of regional development policies in post-reform China, this paper develops the concept and analytical framework of national node strategies （NNS）, defined as regional development strategies centered on specific spatial nodes, by addressing their theoretical basis and re- search scope. The regional economic impacts of NNS were explored quantitatively through the examples of the Shenzhen Special Economic Zone, Pudong New Area and Tianjin Binhai New Area in different stages of the reform and opening up. The results indicate that the evo- lution of China＇s regional development policies can be divided into three stages： the explora- tion stage led by Special Economic Zones （SEZs）, the expansion stage dominated by Eco- nomic Development Zones and the optimization stage featuring State-level New Areas and National Comprehensive Reform Pilot Areas. During all the three stages, NNS have played an important demonstrative and leading role and promoted the rapid evolution of China＇s regional development policies from localized to widespread implementation, and the role of the government has also changed accordingly. As an innovative application and development of the growth pole theory in transitional China, NNS have become engines of regional de- velopment as well as important conduits of institutional innovations. NNS and regional de- velopment have achieved a benign coupling and formed a gradated regional development model. Empirical research indicates that NNS are an important method used by the govern- ment to guide and regulate regional economic development, with complex and diverse eco- nomic effects that differ depending on the stage of regional development and the spatial scale of analysis.展开更多
