新基建作为现代化基础设施体系的重要组成部分,已经成为中国经济高质量发展的重要支撑。基于2015—2021年中国71个城市的面板数据,构建双向固定效应、中介效应和调节效应三种回归模型,实证检验新基建发展对城市产业结构水平的影响及内在机制。研究发现:新基建发展能促进产业高级化水平,改善不合理的产业结构状态,提升产业合理化水平;新基建通过发展物联网和激励城市研发创新两种间接路径对产业结构转型升级产生积极影响;新基建对产业结构水平的影响受到地方政府干预行为的调节作用,在地方政府合理的行政管理下,新基建对产业转型升级的积极作用更为明显;新基建发展对产业结构水平的提升作用具有区域异质性和城市规模异质性,在中西部地区和大城市地区的作用效果更为明显。  相似文献

地方政府“以地谋发展”的策略在促进各地区制造业大规模集聚和出口贸易快速增长的同时,也势必会给企业出口产品质量带来深刻影响。本文综合利用中国土地市场网城市土地交易数据、中国工业企业数据、中国海关进出口产品数据和中国城市面板数据,实证检验了土地市场扭曲对企业出口产品质量升级的影响,并对其内在机制进行了探讨。研究发现:中国城市建设用地配置存在明显的工业偏向性,进而导致工业用地价格被低估,产生工业用地应得收益大于实际价格的反向扭曲问题。这种反向扭曲可通过抑制技术进步、阻碍产业结构高级化、弱化集聚经济效应等机制显著降低制造业企业出口产品质量。土地市场扭曲对企业出口产品质量升级的影响具有明显的异质性特征。具体而言,土地市场扭曲不利于一般贸易企业与混合贸易企业出口产品质量提升,但对加工贸易企业出口产品质量提升具有促进作用。土地市场扭曲对企业出口产品质量升级的抑制作用由东到西依次递增。土地市场扭曲不利于外资企业和国有企业出口产品质量提升,对集体企业及民营企业的影响不显著。  相似文献

Consumers often base their judgments on a no-pain, no-gain principle—that is, one must pay a cost in order to achieve a beneficial outcome. For example, they infer the quality of a product from its price and judge a bad-tasting medicine to be more effective than a tasty one. Although the use of this principle to infer the value of a product or service has been observed in several domains, the processes that underlie its use have not been fully explored. We find that when people feel out of control, they tend to use the principle because it exemplifies a causal relationship between actions and outcomes and endorsing it reaffirms their belief that they have control over the outcomes of their behavior. Our findings have implications for how marketers might position products and services to attract consumers who perceive themselves as having different levels of control.  相似文献

发展“绿色矿业”是人类进入生态文明社会的必然选择,绿色发展理念指导下的“绿色矿业”发展具有主旨统一性和实践多样性、国家主导性和企业渐进性,需要完善的理论指导、体系构建和政策支持。“绿色矿业”的运行体系是由相关主体(绿色政府、绿色企业、绿色社会、绿色市场)及其功能共同形成的网络结构,各主体多元化、多维度的相互作用共同促进“绿色矿业”的有序发展,最终实现“矿业经济发展、生态环境良好、发展成果共享”的目标。我国发展“绿色矿业”的实践取得了显著成效,各地不同的发展模式既有目标的同一性,又有方式的差异性。当前,我国“绿色矿业”发展还存在标准体系不健全、政策法规不完善、发展格局不协调、协同监管不到位等问题,需要进一步发挥政府的主导作用、企业的主体作用、行业协会及社会的协调支撑作用,并构建和优化“绿色矿业链”和“绿色矿业区域板块网络”,推动“绿色矿业”健康有序发展。  相似文献

Purpose: The aim of this article is to elucidate the state of B-to-B marketing research in France by conducting a review of theoretical and empirical studies in this field that have been published over the last three decades.

Methodology/approach: Authors identified relevant literature sources, and proceeded with classifying the publications according to their main theme of study (as determined by reviewing the topic, the abstract, and/or keywords). To extract the main articles, authors explored multiple electronic databases, including Source Premier (EBSCO), Elsevier Science Direct, Google Scholar, and Cairn.info. This methodology has allowed comparisons both in time and in relation to similar works done in other countries. The analysis focuses on the main contributions of French literature in the B-to-B domain and establishes that progress has been made in understanding the issues of B-to-B marketing in France, as well as in the development of the theory in this field.

Findings: The review shows that B-to-B marketing research in France, although under-represented in relation to its B-to-C counterparts, is gradually emerging from the shadows and covers important topics that are increasingly diverse and varied. By identifying the main topics studied by French B-to-B marketing researchers, this work advances this academic discipline while also providing valuable information.

Originality/value: This study is the first attempt to conduct an in-depth examination of the state of B-to-B marketing research in France. Findings yielded by this literature review would be beneficial to both B-to-B marketing researchers and practitioners and promotes this research field.  相似文献

Social scientists have developed several theories for understanding or evaluating policy change over time. Since all costs or benefits are not internalized owing to positive transaction costs, policymaking is always implemented under cost underestimation conditions and, therefore, is imperfect. I call this trait policy failure in this article. Furthermore, I show that a new framework combining the social costs approach and the legal/economic approach in institutional economics is suitable and can be applied to evaluating how past policy failures affect present policy, providing as an example the Fukushima nuclear disaster in Japan.  相似文献

[目的]为促进水库移民的生计恢复及转型,探寻就业结构和土地流转间的交互机制,分析两者间耦合作用对当前移民安置模式及政策的影响。[方法]文章从移民就业结构变迁出发,通过超边际理论构建了安置区移民土地的流转机制模型,推演了从业决策对土地流转行为的影响路径,并运用南水北调农业安置移民数据进行实证检验。[结果]大面积转出土地是移民搬迁后土地处置的主要行为,移民中土地转入户有所增加,但土地集中度却有所减少。移民非农就业较搬迁前有明显上升,并有向当地兼业转移的趋势,但与土地流转间并不互为因果,农村社保还难以弱化其对土地养老的依赖。劳动力数量、非农就业时间、非农收入占比、土地政策等对移民土地流转行为和规模均有显著影响,而外出就业前景和地租水平在促进土地流转行为的同时,却不一定能增加土地流转面积。[结论]移民外迁中可以采用无土安置代替农业安置,推动移民土地流转的关键在于技能培训、政策保障和地租补贴,简单的就业推荐和土地权属划分的作用有限。而对于移民中的农业大户,则需在满足土地转入面积的基础上,保障其在安置区的各项土地权益。  相似文献

[目的]通过对我国北方地区大规模生猪养殖技术效率进行测度,以期发现影响其技术效率增长的主要因素,为我国现阶段生猪养殖业战略性区划调整"南猪北进"工作提供实践指导和理论支持。[方法]根据随机前沿分析方法 (SFA)基本原理,运用对数型柯布—道格拉斯生产函数及我国北方大规模生猪养殖数据构建中国北方大规模生猪养殖随机前沿分析模型,对我国北方大规模生猪养殖技术效率进行测度并据此提出相关建议。[结果]北方地区大规模生猪养殖技术效率值纵向上来看整体在不断下降,而从地域上来看内蒙古自治区和东北地区技术效率值较高,北京与西北地区技术效率值较低。[结论]内蒙古自治区与东北地区适宜作为大规模生猪养殖承载地,与国家政策具有一致性;华北地区与西北地区大规模生猪养殖技术效率测度值较低,存在较大改进空间;针对该现状提出构建经济效益与环境保护并重的规模生态生猪养殖体系。  相似文献

In recent decades, agricultural production in the U.S. has continued to shift to large-scale operations, raising concerns about the economic viability of small and midsized farms. To understand whether economies of size provided an incentive for the consolidation of production, the study estimates the total factor productivity (TFP) of five size classes of grain-producing farms in the U.S. Heartland (Corn Belt) region. Using quinquennial Agricultural Census data from 1982 to 2012 the study also compares TFP growth rates across farm sizes to gain insight into whether observed productivity differences are likely to persist. The finding of a strong positive relationship between farm size and TFP suggests that consolidation of production has contributed to recent aggregate productivity growth in the crop sector. The study estimates the extent to which sectoral productivity growth can be attributed to structural change versus other factors including technological change. The study also explores some tradeoffs associated with policies that raise the productivity of small versus large farms.  相似文献

This study investigates the relationship between internal pyramid structure and performance of Chinese, Pakistani, Malaysian pyramidal firms, the effect of judicial efficiency and minority investor protection on this relationship. The results show that the pyramid structure of Pakistani firms is more complicated than Chinese and Malaysian firms, both vertically and horizontally. The study finds that the impact of control layers on performance is negative and stronger than control chains. Moreover, the results illustrate that the effect of control layers on performance at Chinese firms is negative but lower than at Pakistani and Malaysian firms. However, control chains have insignificant association with performance at Chinese pyramid firms. We find that efficient judiciary abates the negative impact of control layers and chains on performance. Our results reveal that in the absence of efficient courts the minority investors’ protection have insignificant impact on the association between internal pyramid structure and firms’ performance.  相似文献
