Spatial Pattern Evolution and Industrial Characteristics of Economic and Technological Development Zones and High-tech Industrial Zones in China

Economic and technological development zone and high-tech industrial zone are important types of development zone in China,and there are differences in their connotation and goal setting.In this paper,basic data of national and provincial economic and technological development zones and high-tech industrial zones in China were collected and arranged.Kernel density analysis and other GIS spatial analysis techniques were used to analyze the evolution laws of spatial patterns of economic and technological development zones and high-tech industrial zones in cities from 2006 to 2018.First,the agglomeration intensity was compared by measuring the degree of regional agglomeration and dispersion on the two time nodes.Next,kernel density method was used to explore the evolution of the two in the spatial layout and location,and analyze development commonness and difference of economic and technological development zones and high-tech industrial zones.Finally,the trend and reason of spatial evolution of development zones with different leading industries were explored.Research results show that:①the agglomeration degree of layout of high-tech industrial zones is stronger than that of economic and technological development zones,and there are similarities and differences in distribution trend of spatial patterns of the two types of development zones;②the distribution of labor-intensive,capital-intensive and technology-intensive development zones is concentrated at smaller scales and dispersed at larger ones;③although there are differences between the economic and technological development zones and the high-tech industrial zones in the goal,support,structure and function,management system and so on,their spatial development presents a trend of convergence.In the future,when enhancing urban-rural planning and public administration,governments should combine the trend of industrial transformation and upgrading,and optimize spatial layout of development zones by adjusting industrial structure,layout,transportation and land use.

A Study of the Industrial Development in Huazhong Agricultural High-tech Industrial Development Zone

This paper illustrates the current situation and problems concerning the industrial structure in Huazhong Agricultural High-tech Industrial Development Zone,and analyzes the internal contradictions that exist in industry: small-scale land operation has become an inherent obstacle to the industrial development in Agricultural High-tech Zone; farmers are always in a passive position in industrial restructuring optimization; government's policy failures and rent-seeking behaviors have hindered industrial development; the research,popularization and application of agricultural science and technology is not suited to industrial development requirements. Finally,this paper makes the corresponding recommendations for industrial development in Huazhong Agricultural High-tech Industrial Development Zone.

High-tech Industrial Development Zones in Nanjing,Suzhou,Changzhou and Wuxi

Nanjing High-tech Industrial Devel-opment Zone It is a state-level high-tech in-dustrial development zone approved by theState Council, with an area of 16.5 sq km,comprising seven sq km of industrial area,five sq km of Taiwan invested area, three sqkm of university teaching and scientificresearch area and 1.5 sq km of compositeservice area. The development zone is 13.5 kmfrom the city center, with convenient trafficconditions, three state highways and a pro-

Planning mode and realization path of regional characteristic ecoindustrial park

Starting from the regional characteristic industrial park planning plan,a horizontal comparison of domestic and foreign typical urban regional industrial park planning cases is carried out,and the commonalities characteristics are analyzed to explore the regularity and universality of the Tonghua urban characteristic industrial park.Under the guiding principles for planning and development of ecological industrial parks,the city’s resource advantages,industry goals and positioning are studied and analyzed from the perspectives of the government,market,and enterprises.It is pointed out that the government should formulate policies,regulations and the construction of characteristic industrial parks in combination with new planning methods.The market should build industrial parks with the support of industrial stimulus and technological innovation.Finally,it summarizes the realization path of regional characteristic industrial parks from five aspects:positioning and goals,ways to achieve goals,profit models,customers and values,basic advantages and exclusive resources.

山西高新技术产业开发区科技金融创新研究

高新技术产业开发区是推动山西创新产业发展过程中的重要载体,科技金融是建设高新技术产业开发区的重要支撑,是缓解高新技术企业融资难的重要手段。近年来通过不断创新金融产品和金融服务,山西高新技术产业开发区相比之前发展取得了进步,但融资困难依旧是其发展的最大瓶颈,因此研究如何创新科技金融发展模式,充分发挥科技金融对山西高新技术产业开发区推动作用有重要意义。通过分析硅谷、索菲亚、中关村等其他高新区典型的科技金融发展模式,并结合山西高新区科技金融发展的现状,对比梳理出山西高新区科技金融存在的问题,提出了丰富融资方式、推动金融机构多元化等促进山西高新技术产业开发区科技金融发展的对策和建议。
