江西大型企业资本运作模式的现状及其改进对策研究

资本运作是一种有效配置资源、实现企业资本增殖的活动,其核心是产权制度创新。本文对江西大型企业资本运作模式的现状进行了分析,进而提出了一系列的合理的改进对策,以期提高起运作绩效。     

集成本模型、AHP和模糊综合评判于一体的物流中心选址方法

首先建立评价指标体系，对费用指标通过成本模型的遗传算法求解，得出费用可行解，然后利用AHP计算指标体系中其他各项指标权重，综合考虑其他相关指标建立模糊综合评价体系对可行方案进行排序，得到最优方案。     

共同分析师网络与企业异地投资

基于社会网络视角,以2010—2020年中国A股非金融类上市公司为样本,探讨共同分析师网络对于企业异地投资的影响机理及其经济后果。研究发现：共同分析师网络依靠网络中的社会资本及信息传递效应促进企业异地投资,并且这种促进作用在民营企业和第三产业企业中表现得更为明显;经济后果表明,共同分析师网络作用下的异地投资会促进企业创新并提升企业价值,有利于企业健康发展。     

中国政策性创业资本的地位及定位研究

文中将创业资本划分为政策性创业资本与商业性创业资本,提出政策性创业资本不应以追求商业利润或与私人部门分享利润为目标,而是以税收、就业、区域发展、出口和经济发展作为追求目标。它应该承担起更多的社会功能,政策性创业资本的定位就在于通过国家宏观政策方面的调节来分散、分担商业性创业资本的经营风险,吸引、引导、鼓励、扶持商业资本进入创业投资领域。     

产业空间集聚的理论发展

产业空间集聚的本质是经济行为主体相互选择的结果.从主体策略选择的角度对产业空间集聚的理论研究进展进行诠释,体现了行为主体在空间区位上的策略均衡,也体现了空间经济理论的研究传统.作为经济干预主体的政府,其介入影响着微观经济主体的空间策略,从这一理论角度出发,阐述转型发展中经济资源的空间配置问题具有特定的现实意义.     

一种适用于高铁沿线的多台站快速地震预警方法

对于地震预警技术来说,根据参与监测预警的台站数量不同,可以将高速铁路地震监测预警系统分为单台站地震P波预警技术和多台站地震P波预警技术。单台站P波预警由于信息量较少以及噪声影响,在定位方面存在较大误差。多台站P波预警技术是在单台站P波预警的基础之上,综合多个单台站信息进行综合震源参数估算并发出地震预警信息的预警方式。通过应用多台站P波预警定位技术,能够在震源估算方面得到更准确的结果。     

Who are better monitors? Comparing styles of supervisory and independent directors

This paper compares the unobservable style effect between independent directors and supervisory directors on firm performance. Utilizing the unique Chinese board system with both independent and supervisory directors and a large panel data of 2,240 public firms from 2003 to 2017, this paper finds that both supervisory and independent style is crucial in determining variations of firm performance. The effects of both independent and supervisory director style are less significant when the “type II” agency problem is more severe in a firm. Moreover, outside independent director style is more effective when information costs are low or when firms need more outside resources, while inside supervisor director style is more effective when there are no major internal changes. Finally, the results also suggest that increasing qualified supervisor representations are beneficial to firms.     

Policy options for afforestation in Flanders

This paper analyses current and alternative afforestation policy instruments in Flanders. First we select forest sites that maximize net social benefits given a constraint on the total area of new forests and then we select policy instruments that yield this optimal combination of sites. For each policy option, we calculate the associated costs for landowners and government as well as net social benefits for society. Our empirical illustration shows that the welfare gain is considerable if the afforestation subsidy is conditioned on an objective criterion rather than a case-by-case approach. Our results also show that it is worthwhile to consider alternative policy instruments, such as auctions, not previously used in Belgian legislation.     

Russia: Firm entry and survival barriers

Why are there so few new firms in Russia? This paper provides further insights into the specific Russian business landscape and how it impacts the low level of new firm entry. As this paper indicates, internationally comparative data do not provide many clues, since in terms of purely formal constraints Russia fares comparatively well. However, a deeper analysis uncovers the informal impediments associated with the lack of rule of law, inconsistent enforcement of regulations, regional autonomy and pervasive corruption. These informal constraints form impediments not only for new firm creation but also for firm survival and firm exit.     

The Downside of Knowledge Spillovers: An Explanation for the Dispersion of High-tech Industries

Both theoretical work on knowledge spillovers and regional policy initiatives often assume that there exists a general and unanimous advantage for firms to cluster. But opposed to the benefit is the disadvantage of sharing knowledge with other (rival) firms. This paper highlights the “downside” associated with knowledge spillovers and presents a four-stage game of location choice where spillovers result from labour poaching and where the strategic interaction between firms may make them avoid co-location with spillovers. The model provides an explanation for the dispersion of German high-tech industries found in a companion paper.
