根据企业核心竞争力理论.对于区域经济研究而言.提供了理论基础.用以研究省域提供了沿源思路。笔者认为:省域是指省域内部一系列互补的资源、产业和知识的结合.它具有使一项或多项优势产业达到竞争领域一流水平。它是省域在一系列发展过程和各种决策中形成的.具有自己独特优势的技术、文化和机制所决定的巨大的资本能量和经济实力.省域表现在区域经济绩效、政府效率、企业效率和区域内基础设施上.  相似文献

从技术要素角度分析FDI对省域产业结构调整的影响具有十分重要的理论意义和现实意义。理论分析表明,FDI对省域经济具有技术溢出效应,通过这种效应会促进省域产业结构的调整。河南省经济运行数据的实证分析也表明,FDI对河南省产业技术进步和产业结构的调整具有重要作用。因此,为了促进省域产业结构调整,河南省在引进FDI时应该加强技术引进、提高企业的技术吸收和创新能力。  相似文献

中国电力产业区域技术效率及其影响因素分析   总被引:2,自引:0,他引:2  
文章基于Metafrontier生产函数模型,采用中国31个省市2000-2010年的面板数据,对电力产业区域技术效率进行了比较分析,并利用托宾模型分析了电力产业区域技术效率的主要影响因素。结果表明:中国电力产业区域技术效率具有40%左右的改进空间,且东、中、西地区的电力产业技术效率呈收敛趋势。相比而言,东部和西部地区电力产业技术效率高于中部。此外,工业比重、技术进步、开放程度等因素对电力产业区域技术效率具有正面的促进作用,而经济规模对电力产业区域技术效率具有负面作用。  相似文献

基于深度稀疏自动编码器构建中国省域智慧乡村发展潜力评价模型,并运用泰尔指数分解、核密度估计、遗传算法等研究方法对智慧乡村发展潜力的时空格局、分布动态、影响因素进行分析。研究表明:①中国省域智慧乡村发展潜力整体处于中等(Ⅲ级)水平,且各省域智慧乡村发展潜力呈“橄榄型”分布。②中国省域智慧乡村发展潜力快速提升,部分起点低、增长快的省域实现“弯道超车”。③中国省域智慧乡村发展潜力呈东-中-西阶梯下降的空间特征,区域间差距是造成分异的关键。其中,东部地区已进入成熟阶段,各省域分布呈多极化趋势;东北地区、中部地区处于快速发展阶段,东北地区各省域分布相对均衡,中部地区头部省域表现突出而落后省域并未取得显著提升;西部地区处于早期发展阶段,各省域分布呈两极分化趋势。④农村电商产业发展、农村消费水平提升、农业现代化推进与农业技术创新是影响中国智慧乡村发展潜力省际差异的关键因素。  相似文献

应急产业是列入“十四五”国家安全体系建设的保障性产业,是科技赋能应急管理的基础。运用DEA-Malmquist指数测度2011—2020年中国省域层面应急产业创新绩效的时空演化趋势。结果表明:在趋势变化上,近10年应急产业创新绩效总体呈下降趋势且波动较大,政策调整及重大社会事件很可能是提振创新绩效的核心诱因,技术效率变化常常滞后于技术进步变化;在空间态势上,呈现“东部较强,西部居中,中部靠后”空间格局,其中东部地区能够有效把握关键事件的“窗口期”提升创新绩效,西部地区技术效率增效明显并进入发展加速期,中部地区则表现欠佳。  相似文献

中部地区承接东部产业梯度转移的壁垒与对策   总被引:3,自引:0,他引:3

受国际产业转移和国内经济转型的影响,东部部分劳动密集型产业向中部加速迁移,我国区域产业梯度转移面临着新的调整与选择。中部有承接东部产业转移的地缘优势、资源条件和产业基础,正面临着承接东部产业梯度转移的重大历史机遇。东部产业向中部转移仍存在诸多壁垒,制约了东中部产业深度分工和要素优化配置,阻碍了东部传统产业向中部迁移。东部和中部地区政府应进行政策调整和制度创新,推动区际产业转移和区域经济协调发展。  相似文献

Recent years have witnessedsignificant changes in the Asia-Pacific regionalstructure featuring the shift in power balance among related countries as well as adjust-ments in their respective regional strategies. So what is the prevailing trend in thistransformation and what kind of regional order will likely emerge in the future? To an-swer these questions, the paper tries to explore the following dimensions: the evolvingregional context, shift in power balance and power conversion, geo-political and geo-e-conomic developments and interactions between them, and evolving regional order. Asthe study shows, the broadening of regional geographical scope, the rise in the numberof actors involved, as well as changesin the relations among them, have combined tocast a pluralistic and complex flavor to the regional structure. While the power balanceamong China, the United States and Japan shifts, and power conversion is also occur-ring. China and Japan are paying increasing attention to their security roles, whereasthe United States under the Obama administration laid more stress on expanding itsgeo-economic clout. In spite of the intensifying geopolitical competition among China,the United States and Japan in recent years, a Sino-US strategic compromise-whichholds the key to regional geopolitics-isother front, some kind of geo-economicmore likely to take place in the future. On thecooperation will probably emerge. In the longerterm, it will be the geo-economic trend thatwill prevail over the geopolitical trend inthe region. Finally, the future evolution of regional order wiI1 mainly follow the eco-nomic logic, accompanied by the dilutionof its hegemonic and hierarchical nature.Hence, a pluralistic and complex regional community will emerge.  相似文献

The British Navy in the age of sail was the most successful bureaucracy of its time. Its organization and incentive structures differed importantly from contemporaneous private sailing ventures, but closely resembled those of today’s large corporations. To induce efficient effort, the navy used a hierarchical tournament, in which sailors competed for higher pay that came with promotions based on relative performance. Promotion probabilities, the option value of future promotions, and the higher effort required of men in higher ranks and on larger vessels, combined to yield a highly skewed pay structure.  相似文献

Abstract

The Hanseatic League and her kontors (trading posts) were an integral part of the medieval trade system in Northern Europe. Hanse merchants dominated many markets in this region and managed to maintain a monopoly-like role in towns like Novgorod and Bergen for many centuries. Consequently, one focus of historical research about the Hanseatic League lay on the mechanisms that enabled the Hanse merchants to keep that strong of a position for such a long time.

This article is part of the discussion about this topic. Based on Lübeck merchants with business interest in the Norwegian town of Bergen, the so-called Bergenfahrers (Bergen travellers), it will give new insights into the Hansards' economical and social organization. The three main points are (a) the integration of the Bergen market in the Hanseatic trade network as an intermediary trading place on the vivid East–West route of Hanse trade; (b) the importance of the Bergenfahrers within the Hanse merchants' economical, social and political networks; and (c) the structure of the Bergenfahrers network patterns in the late Middle Ages.

In addition to new insights into the important role of Bergen and the Bergenfahrers within Lübeck's and the other Wendish Hanse towns' trading system, this articles provides further proof for the usefulness of the methods of Social Network Analysis in medieval economic research.  相似文献

We investigate the effect of mandatory IFRS adoption on trade credit. We document that firms in countries that adopt IFRS receive more trade credit from their suppliers, consistent with improved financial reporting quality and comparability playing a role in facilitating informal financing. This increase is larger for countries with a low level of societal trust, a poor pre‐IFRS‐adoption information environment, and stronger legal enforcement. These cross‐sectional results suggest that the conditions under which higher‐quality information is made publicly available affect suppliers' decisions to provide trade credit. This increase is also larger for firms with greater exposure to foreign markets, a finding that highlights the importance of more comparable international financial reporting standards in facilitating cross‐country trade credit. We also find that IFRS adoption has a stronger positive effect on trade credit for firms with greater liquidity needs. Finally, we find that firms in countries that adopt IFRS also extend more trade credit to their customers. Overall, our results support the notion that financial reporting can have a causal effect on trade credit.  相似文献

The bio-control potential of rhizospere bacteria Pseudomonas fluorescens against plant-parasite nematode had been demonstrated. P. fluorescens had shown the effect to enhance tobacco resistance to root-knot nematode Meloidogyne incognita. Inoculation with P. fluoreseens in tobacco could lead to significant reductions in the number of juveniles that penetrated tobacco root and further life stage development of the juveniles. The number of juveniles penetrated into tobac- co root in treatment with P. fluorescens is significantly different from CK at 2DAI, 6DAI, 8DAI and 10DAI. Significant reduction and delayed development of juveniles that penetrated into tobacco root and treated were observed in treatment at 14DAI, 21DAI, 28DAI and 35DAI. In addition, P. fluoreseens treatment leads to a significant reduction in the number of eggs per egg-mass at 35 DAI. The results show P. fluorescens induced a continuously suppression on root-knot nema- tode M. incognita throughout their entire early infection phase of root penetration, subsequent life stage development and reproduction.  相似文献
