Development zones have been an important spatial approach to promoting economic development since China's reform and opening-up. They have also been major contributors to the processes of China's industrialization and urbanization. Along with improvements in the worldwide industrial division of labor and the gradual implementation of China's development zones' Go Global strategy, it is necessary for Africa, a hot spot of global industrialization in recent years, to learn from China's development zone model. By attracting China's capital, technology and enterprises to Africa via Sino-African co-built development zones, a pattern of high complementarity and mutual development between China and Africa can be formed which does favor further improvement of the global industrial division of labor. In order to study the applicability and prospect of China's development zone model in Africa as per the above-mentioned international situation, this paper first sorts out the development course of China's development zones and discusses their roles in China's industrialization and urbanization. Subsequently, this paper analyzes the status quo of industrial development in Africa as a whole and the differences in industrial development between China and Africa, aiming to justify the timing of industrial transfer from China to Africa by constructing Sino-African co-built development zones. Lastly, this paper analyzes the current situation of six Sino-African co-built development zones by focusing on their operation modes, industry types and investment promotion models. In the authors' view, Sino-African co-built development zones can function as a new window of China-African cooperation, a new carrier of African industrialization, and a new engine of global industrial restructuring. China should adhere to the general principles of ‘Sino-African Integration, Multi-Cooperation, Mutual Benefit, Scientific Location, Systematic Planning, Cluster Growth and Open Development' in the planning and construction of development zones in Africa, effectively promoting Africa as the very important part of the global industry system. 相似文献

The second-tier extended metropolises in the Changjiang (Yangtze) River Delta, including Suzhou, Wuxi and Changzhou near Shanghai,
are becoming the most active and new innovative industrial agglomerating areas. Manufacturing industries in these second-tier
cities have been in rapid growth due to increasing foreign investment. Nevertheless, the economic prospect of these cities
is still constrained by a lack of local R&D capacity and production services, which are mainly dependent upon Shanghai. This
paper analyses the impact of globalization on the new economic sectors in these cities, the change of industrial structure,
the limitation of urban development and the problem of sustainability. Then, the paper analyses the conditions for the high-tech
industry and production services in these areas. Also, it applies the industrial organization theory to these cities and examines
how these cities can cooperate with each other in terms of horizontal linkages. Finally, the paper gives the future growth
prospects in high-tech industry and production services.

So-called free economic region is a special region without jurisdiction of customs, delimited by one country. There are mainly
four types of free economic region, that is, commercial type of free economic region —free port, industrial type of free economic
region — export processing area, integrated commercial and trade type of free economic region — free trade zone, and scientific
and technological type of free economic region — scientific industrial park. With the development of free economic region
of different countries, besides free economic region within one country, there appear transnational border free economic region
established by two or multiple countries. Analysing favorable factors and unfavorable factors to establish the free economic
region for China and Russia, for example, China and Russia have land boundary line of 4282.7 km; China and Russia may strengthen
overall cooperation in politics, military, economy, science and technology, culture, etc. making full use of geographical
factors of the two countries, borders; there is a strong complementarity in resources, labour force etc. for China and Russia;
strengthening the Sino-Russian economic trade cooperation is needed, the authors proposed a conception and selected four comparative
ideal locations for establishing the Sino-Russian border free economic region: Manzhouli-Zabaikalye Free Economic Region,
Heihe-Blagoveshchensk Free Economic Region, Suifenhe-Pogranichnyy Free Economic Region, Hunchun-Hasan Free Economic Region.
Finally the principles and patterns for establishing free economic region are discussed. 相似文献

Using datasets on high-tech industries in Beijing as empirical studies, this paper attempts to interpret spatial shift of high-tech manufacturing firms and to examine the main determinants that have had the greatest effect on this spatial evolution. We aimed at merging these two aspects by using firm level databases in 1996 and 2010. To explain spatial change of the high-tech firms in Beijing, the Kernel density estimation method was used for hotspot analysis and detection by comparing their locations in 1996 and 2010, through which spatial features and their temporal changes could be approximately plotted. Furthermore, to provide quantitative results, Ripley′s K-function was used as an instrument to reveal spatial shift and the dispersion distance of high-tech manufacturing firms in Beijing. By employing a negative binominal regression model, we evaluated the main determinants that have significantly affected the spatial evolution of high-tech manufacturing firms and compared differential influence of these locational factors on overall high-tech firms and each sub-sectors. The empirical analysis shows that high-tech industries in Beijing, in general, have evident agglomeration characteristics, and that the hotspot has shifted from the central city to suburban areas. In combination with the Ripley index, this study concludes that high-tech firms are now more scattered in metropolitan areas of Beijing as compared with 1996. The results of regression model indicate that the firms′ locational decisions are significantly influenced by the spatial planning and regulation policies of the municipal government. In addition, market processes involving transportation accessibility and agglomeration economy have been found to be important in explaining the dynamics of locational variation of high-tech manufacturing firms in Beijing. Research into how markets and the government interact to determine the location of high-tech manufacturing production will be helpful for policymakers to enact effective policies toward a more efficient urban spatial structure. 相似文献

城镇-农业-生态空间划定(简称"三区"划定)是国土空间规划的核心内容,对于科学合理地规划、利用有限的国土资源具有重要的意义。已有研究主要根据区域内土地利用与社会经济发展现状构建指标体系进行"三区"划定,较少将未来土地利用变化纳入"三区"划定过程中,使得划定结果在指导实践过程中缺乏前瞻性。针对这一问题,本文提出一种基于土地利用情景模拟,结合指标体系评价与决策树特征挖掘的"三区"划定方法,并以武汉市2015年土地利用现状为基础,在土地利用变化情景模拟的基础上进行"三区"划定。通过对比,验证了本文提出方法的合理性。研究发现:①不同情景下的"三区"空间在规模、空间分布上具有明显差异,将未来土地利用变化纳入"三区"划定过程中确有必要;②不同土地利用情景下"三区"空间的差异主要出现在三类空间的交界区域,这些区域是国土空间规划应该关注的重点区域。 相似文献

In China, the urban industrial district is usually an organic concentrated district including many factories that are in big,
middle or small size, and are coordinated in the process of production, or use infrastructure in common. The formation and
development of the urban industrial district in China are affected by not only general factors such as natural factor, transportation
factor, labour factor, ecologic factor, but also special factors such as agglomeration factor, technologic factor and social
factor. To the district’s formation, both the social factors and natural factors are important, especially the attitude the
government have towards the district and the regional natural condition. But the agglomeration, market and transportation
costs here are not as important as those in the traditional Industrial Location Theory. Now we must pay great attention to
these three factors owing to the new economic conditions in China. In the development of the district, the main factors are
technology and agglomeration. This indicates that the technologic factor is gradually the essential condition in the development
of the district. Besides, we must also know the affection of the ecologic factor in the development of the district. According
to the reality of Caohejing district, this paper gives every factor mark in the Analytic Hierarchy Process (AHP). With the
result of the AHP, some suggestions have been put forward to Caohejing Hi-Tech Park and other urban industrial districts as
well. 相似文献

There is a great difference in starting conditions among Hainan Island, the special economic zones and the economic and technological development zones in China, and "the Four Small Dragons" of Asia. Hainan's major superiority is superiority of the special economic zone. The superiority includes two main parts of natural resources and geographical location. In order to give play to the superiority it is necessary to develop the export-oriented economy. As for giving full play to the location superiority, it must be solved that the problems on the investment, the talent and the development models. It is very important to rely on the superiority of natural resources to develop the products which is necessary for our country and can replace the imports. The rational adjustment on the economic departments in Hainan Province comprises two aspects. The departments of exploiting natural resources must enlarge the processing depth of agricultural products and industrial raw materials, and increase the additiona 相似文献

Since China opening to outside world, the economy in the Pearl(Zhujiang) River Delta(PRD) has been dou-ble digit growth. It has been known as one of mature fast growth areas in the world and become the model and hope of Chi-nese reform and opening to outside world. The regional development in PRD is the outcome of polarization effects. The polar-ization effects actually are extension of international regional division and a combination of Hongkong‘‘s influence and re-form and open-door policies on the mainland. Since the 1990s, driven by knowledge-based economy, the PRD has furtheradjusted the industrial structure and achieved good progress in upgrading industrial structure. Its high technology industryhas developed quickly and the economic internationalization has deepened, meanwhile, the region is going through transforma-tion and some new trends have begun to appear, which include: university towns springing up, industrial globalization andthe construction of Hi-tech development zones. The paper suggests that with the economic growth changing from relying onthe low level production elements to relying on high level production elements, the regional policies in GuangdongProvince should develop correspondingly: 1) make a plan to prohihite the blind construction in innovative spatial construc-tions; 2) make measures to attract the overseas talents to establish a pool of talent; 3) work out the favorable policies forabsorbing larger capital; 4) formulate the policy of attracting a cluster of industries to speed up the upgrade of industrialdevelopment. 相似文献
