浅谈如何提高汽车的燃油经济性

目前,绝大多数汽车都是消耗燃油的,随着汽车保有量的增加,汽车消耗的燃油占石油产品消耗量越来越大,如何减少对石油产品的消耗,节约石油资源已成为举世瞩目的问题,而且从汽车使用的单位和个人角度来讲,降低燃油的消耗也是至关重要的,因此,我们有必要分析一下影响汽车燃油经济性的因素及提高汽车的燃油经济性的措施。     

市场经济条件下的铁路交通运输经济管理

Proposition of a structural model for business value creation based on circular business models,innovation, and resource recovery in the pet industry

Based on the assumptions of circular economy, resource recovery, and innovation, the aim of this research is to analyze the relationship between innovation constructs, resource recovery practices, Circular Economy Business Models (CEBMs), and value creation in a fast-growing emerging economy. A set of empirical data from 443 companies in the pet industry were used. In terms of methodology, the study was processed using the SPSS software, using Structural Equation Modeling, with manipulation of primary data. CEBMs demand greater engagement, internalization of initiatives, and synergy with the operating ecosystem of the pet industry. Innovation is present but has the potential for expansion through adherence to the innovation ecosystem and its technological package, partnerships, and relationships so that companies can scale up and create value with the support of resource recovery practices. The results of this study can be useful for companies in the pet industry, as it allows the identification of areas and practices that require their attention to improve organizational performance and create value for the business based on initiatives supported by the assumptions of circular economy and sustainability.     

THE LIMITS OF INFRASTRUCTURE: Public Transport in a Post-colonial City

Since the 1940s, the people of the neighbourhoods (kampungs) around Surabaya's derelict Ngagel industrial estate have made a living by repurposing the remains of what was once one of Asia's most modern road, rail and industry networks. The remains—in the form of leftover fuel, labour and factory parts—are used to rebuild and repair improvised transport vehicles like bicycle-taxis (becak), minibuses (bemo) and motorbike-taxis (ojek). The repurposing happens at the limits of a capital-intensive heavy infrastructure of factories, trams and buses. The limits are those points where such infrastructure fails and a household-funded mosquito-fleet of light vehicles succeeds. Repurposing gives those who do it a right to infrastructure by providing the city with much-needed public transport. In Surabaya, public transport begins at its limits through the improvisations of people who live in the productive remains of capital-intensive heavy infrastructure. These people live in Surabaya's deindustrialized urban core, where life is made in the ruins of infrastructure through the breaking-down of it, the reworking of it, the right to it, and the leakage of it—the means through which rank-and-file people rather than states and corporations forge infrastructure.     

鄂苏浙粤鲁省域中小企业群比较

以省域中小企业群为样本,通过湖北与东部省份的比较研究,中部经济总量与东部经济总量产生巨大差距的一个重要原因是中小企业群体数量偏少和成长能力不强。中部中小企业发展不充分的原因在于微观成长机制不强和中观环境支持不够。最后提出促进中部地区中小企业发展的政策建议。     

数字经济是否促进了中国的城乡融合——基于中介效应模型与空间杜宾模型的检验

城乡融合是破解社会主要矛盾、实现高质量发展的必由之路,蓬勃发展的数字经济为城乡融合提供了新动能。本文测度了2011~2020年中国30个省市的城乡融合和数字经济发展指数,在分析数字经济对城乡融合影响机理基础上运用中介效应模型和空间杜宾固定效应模型来检验数字经济对城乡融合的影响。结果表明：数字经济对城乡融合产生显著的正向影响,并通过改善资本要素错配和数据要素错配对城乡融合形成间接促进效应。最后,空间杜宾固定效应模型发现数字经济对城乡融合的积极影响存在空间溢出和区域异质性的特点。因此,应推动数字技术在农业、医疗、教育、电商等领域的应用,加强资源共享,构建数字经济普惠格局,打破城乡分割的“藩篱”,助推区域协调,最终实现城乡融合。     

旅游经济增长因素的空间计量研究

文章在文献分析的基础上,构建了旅游经济增长影响因素的空间计量模型,并运用2000—2009年大陆31个省、市、自治区的数据进行实证研究。结果表明：在考虑空间效应的影响下,我国旅游经济增长具有空间依赖性,其中2000—2008年出现正的空间溢出效应,2009年出现负的空间溢出效应;旅游业发达省份旅游经济增长速度低于欠发达省份,低增长和高增长省份在空间上聚集。旅游接待设施数量的增加、居民消费水平的提高对旅游经济增长具有显著的促进作用;旅游景区数量的增长对旅游经济的增长作用不显著;而交通里程的增长对旅游经济的增长具有反向作用。     

论经济与文化的耦合与发展

精神层面的文化对一国经济社会的发展特别重要。本文从经济学角度论述了精神层面的文化对于经济社会发展的重要意义,文化的特征,与市场经济相适应的文化、我国传统文化的特点等问题。论文认为对传统文化必须通过改造使之与社会主义市场经济相适应,而不是囫囵吞枣地接受。
