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.

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.

科技创业促进要素市场化配置的逻辑、路径与对策

本文在现有文献基础上概括提出“科创经济”的术语概念,并提出科技创业是科创经济时代深化要素资源配置市场化改革的一种新方式,是比传统方式更适应市场化的要素配置机制。科技创业是促进经济增长与发展的核心动力,不但可带来生产生活的重大变革,而且可带动市场需求和技术创新,促进经济焕发新活力并取得新发展。科技创业可经由提升就业活力和优化生产力系统等多个方面,促进要素市场化配置,优化我国经济结构,助推全国统一大市场建设,从而促进我国经济可持续地高质量发展。科技创业亟须通过加大风险投资、加强环境支持、纠正科研导向、减少障碍约束来获取更大推动力。

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。
