本文通过界定区域智慧专业化产业的特征,以31个省份的权威统计面板数据为基础,从4个维度15个指标出发,运用改进的信息熵权TOPSIS法,构建了区域智慧专业化评价指标体系与区域智慧专业化评价模型。结果表明,东中西部区域智慧专业化水平表现出明显的地区差异,东部省份区域智慧专业化水平都较高,广东省的智慧专业化水平最高,西部省份区域智慧专业化水平都较弱,且智慧专业化发展水平高的区域与发展水平一般的区域存在较大的极化现象。以智慧专业化理论为基础,基于区域智慧专业化发展水平评价和智慧专业化指数得分,对比国外智慧专业化的发展现状及特征,结合国内创新驱动发展战略,进一步深化区域智慧专业化的研究内容。 相似文献

基于对以科技企业孵化器为核心的创业生态系统分析,探索科技企业孵化器生态位的内涵,从经济、人才技术和社会资源3个维度构建科技企业孵化器生态位评价指标体系,对我国30个省份科技企业孵化器发展水平进行实证分析.结果 表明:各省份科技企业孵化器综合生态位排名的空间分布格局与其经济水平的空间分布格局基本一致,均为由东部沿海、中部至西部依次降低;各省份科技企业孵化器由于发展的资源基础和起步时间不同,态值差异远大于势值差异,在经济维度的差异更为显著;根据不同生态因子,我国科技企业孵化器可划分为5类且各具特征.最后对我国科技企业孵化器未来发展提出建议:持续推动创业孵化生态不断优化,充分发掘利用本地资源禀赋,抓重点、差异化全面提高孵化器发展水平,以及在融合共生中共同发展等. 相似文献

作为高技术制造业的延伸和现代服务业的高端环节,高技术服务业对于扩大内需、促进产业转型升级具有重要意义。为了测度我国高技术服务业区域发展水平,本文从基础条件、产业结构、创新投入和创新产出四个维度,构建了包含4个一级指标、18个二级指标的评价指标体系;采用因子分析法提取高技术服务业发展水平的主要因子,并利用基于加权马氏距离改进的聚类分析方法对我国各省、市、自治区的高技术服务业发展水平进行综合评价。结果表明：我国高技术服务业区域发展不平衡,尤其在产业规模、基础条件与创新环境方面差异明显。据此将我国31省、市、自治区的高技术服务业发展水平划分为四个梯队,并分别从政府、各梯队区域内和区域间三个角度提出了政策建议。 相似文献

湖南省主体功能区划分及发展策略研究 总被引：1，自引：0，他引：1
根据湖南省区域发展状况,参照"十一五"规划《纲要》的主体功能区划分基本思路,从资源环境承载力、开发密度和发展潜力等因素出发,确定了区域主体功能区划分的指标体系。以湖南省14个市(州)为基本空间单元,运用状态空间法对该区主体功能区进行了划分研究。结果表明:除依法设立的各类自然保护区散布在各地市外,优化开发区主要集中在东部地区,重点开发区主要分布在中部和南部地区,限制开发区则集中在西部地区。研究结论为:优化湖南省空间开发结构,协调区域发展,实现生态环境的可持续发展具有重要参考。 相似文献

《全国主体功能区规划》颁布实施后,为不同类型的主体功能区选择适宜的绩效评价方法成了亟待解决的问题。以位于乌蒙山区的贵州省毕节市三个连片县域为实证区,三个县域分别被规划为重点开发区、农产品主产区和生态功能区,本文旨在探讨不同类型主体功能区绩效评价创新方法。依据主体功能区规划划分理论框架,从分别代表现有发展程度、未来开发潜力和资源环境承载力的区域经济发展、社会发展和资源环境效益三个方面选取15个指标构成绩效评价指标体系,运用BP人工神经网络构建评价模型,依据主体功能区规划区别开发的原则对不同类型主体功能区采用不同的评价标准和训练样本。结果显示,三个实证县域绩效水平相差较悬殊,七星关区(重点开发区)绩效水平远高于其他两个县,得分在0.6～0.7之间;赫章县(生态功能区)是三个实证县中得分最低的地区,五年间得分均低于0.3;大方县(农产品主产区)绩效介于两地区之间,得分在0.2～0.6之间。最后,本文在评价结果基础上分析三个县域发展现状成因后,结合各区域的自然条件、产业基础及开发潜力,以乡镇为单位提出了各自的区域发展优化模式,绘图展示出实证区产业开发空间布局。 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

The research into the origins of domestic animals is of significance not only for understanding their development per se but also for making clear the human society evolution. Although there are evidences to show that pigs were independently domesticated in a variety of places throughout the world the detailed scenario of the origin dispersal of domestic pigs in East Asia remains unclear.…… 《中国科学院院刊(英文版)》2008,22(1):7-7

Prof. SUN Changpu from the CAS Institute of Theoretical Physics coworkers from University of Basel in Switzerland have worked out a way - at least in theory - to split a beam of molecules according to their chirality. The technique involves passing the molecules through three different laser beams is similar to the famous Stern-Gerlach effect whereby a beam of atoms passing through a magnetic field is split in two according to the atoms' spin states 《中国科学院院刊(英文版)》2008,22(1):23-23
