Analysis and Research on Industrial Land Transfer in Hefei City Economic and Technological Development Zone of Anhui Province

In recent years,with high-speed development of economy and society,and fast propulsion of industrialization and urbanization process in the development zone,average annual land demand in the development zone also quickly enlarges,and the contradiction between high-speed growth of economy and shortage of land resources is apparent increasingly. Meanwhile,to guarantee crop safety and stick to 0. 12 billion hm2of farmland red line as a rigid constraint which could not be exceeded,the supply-demand contradiction of industrial land is more and more prominent. With industrial land scale continues to enlarge,land resources become more and more scarce,but there exists the phenomenon of low-efficiency land use and even idle. For land use characteristics of the development zone,taking Hefei City Economic and Technological Development Zone as an example,the countermeasures of perfecting industrial land transfer mechanism in the development zone are proposed.

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.

Strategies to Promote Sustainable Development of Industrial Parks in Vietnam＇s Northern Key Economic Zone

Industrial Parks （IPs） in the Northern Key Economic Zone of Vietnam （NKEZ） have been making significant contributions to the development of the zone since the first two industrial parks--Noi Bai in Hanoi and Nomura in Hal Phong--were established 15 years ago. So far, there have been 51 IPs in the zone, covering a total area of 13,000 ha. Such IPs play a crucial role in mobilizing capital from domestic and international investors for investments in infrastructure enhancement, trade and production aimed at promoting the economic structure transition. However, besides the above benefits, there are a number of unstable factors preventing further development of the IPs. Thus, the objectives of this study are two-fold. The first is to analyze the unstable factors, and the second is to map out strategies to enhance sustainable development of industrial parks in Vietnam＇s northern key economic zone.

尺度重构视角下经济技术开发区向综合功能新区转型的空间应对——以烟台黄渤海新区为例

鼓励和促进经济技术开发区向综合功能新区转型发展,是经开区空间生产转型的内在需求,也是响应国家对经开区发展定位的重要举措。本文基于尺度重构理论视角,以烟台黄渤海新区为例,总结分析经开区向综合功能新区尺度重构的基本逻辑。研究认为,经开区向综合功能新区转型发展的过程,是一次“尺度上移”的过程,通过赋予更高层级的管理权限,重构区域生产关系、社会关系以及治理关系,形成产业协作有序的功能板块、更高标准的产城格局以及更加扁平化的治理结构。研究发现,烟台黄渤海新区在建设过程中,面临多空间主体及多政策制度并存的治理难题,其空间呈松散发展状态,以及低水平的产城融合特征。据此,文章提出整合港产功能板块、调整产城关系以及实施渐进性治理机制的治理策略,推动新区高质量发展,打造带动区域经济高质量发展的重要增长极。

Scale,Site Selection and Function of Economic and Technological Development Zones

This article analyses different characteristics of scale,site selection and function of the current economic andtehnological development zones in our country.It further proposes that it is inappropriate for the economic andtechnological development zones to follow the“pattern of the special zones”,but a new pattern of“small scale,unitaryfunction and closeness to old city”should be adopted to fit in with the practical conditions in our country.The scale,landuse structure and the relations between the development zone and the old city are the basic issues in planning forthe development zones.These three essential elements constitute the pattern of planning which determines to a certainextent the success or failure of the development zones.

经济开发区与城市普惠金融:影响效应与作用机制

作为一项应用广泛的区域性产业政策,经济开发区对城市普惠金融的影响尚未定论。通过网络爬虫技术搜集金融许可证信息,并结合城市统计年鉴和开发区审核公告目录等数据分析经济开发区对我国城市普惠金融的影响及其作用机制。研究发现,经济开发区的设立显著地促进了我国城市普惠金融的发展,且其结果是稳健的。进一步的异质性分析表明,省级开发区比国家级开发区的影响效应更显著,中西部地区设立经济开发区比其他地区的促进作用更显著。机制检验表明,经济开发区的设立通过提高财政支出占比、推动交通基础建设和提高城市居民平均收入这三个渠道促进了我国城市普惠金融的发展。研究结论可以为新时代下我国经济开发区政策的优化、高质量普惠金融体系的构建提供有益参考。

经济技术开发区升格、产城融合与城市创新水平

城市创新水平的提升离不开产业与城市协调发展,因此在评估地方经济技术开发区升格为国家级经济技术开发区对城市创新的影响作用时,应当考虑产城融合的情况。基于此,将省级经济技术开发区升格为国家级开发区作为一项准自然实验,依据2018年版《中国开发区审核公告目录》,从产城融合视角出发,采用多期双重差分模型考察2009—2019年我国经济技术开发区升格对城市创新水平的影响及其作用路径,并通过平行趋势检验、安慰剂检验等方法进行多种稳健性检验验证。结果表明:开发区升格有效促进其所在城市的创新水平提高;产城融合是升格开发区所在城市创新增长的重要原因,主要通过促进服务共享、要素畅通和协同创新等发挥作用;受地理区位、发展水平影响,开发区升格带来的城市创新数量和创新质量促进效应有所差异;此外,开发区升格政策还具有线性叠加效应,随着开发区升格数量的增加对城市创新的推动作用增强。因此,各地方政府应结合本地区发展实际加快推进开发区升格工作,加快产城融合和产城互促。

差异性开发区管理体制的影响要素分析——基于区城互动的视角

开发区的管理体制不同于传统行政区,具有其特殊性。本文基于区城互动视角,研究发现城市政府影响了所在地开发区管理体制的形成,具体体现为强规制“政府导向”与弱规制“市场导向”两种形态。本文以“城市环境—开发区基础”为核心要素,以区城互动为视角,构建了开发区管理体制的分析框架,并基于14家首批设立的国家级经济技术开发区,运用模糊集定性比较分析法和多时段定性比较分析法,对影响开发区管理体制的因素及条件组态进行探讨。研究发现,开发区管理体制的形成具有“母城依赖型”“区城互动型”“规模经济型”三种模式,该研究结论为我国开发区管理体制类型的解释与选择提供了理论与实证支撑。
