中国服务业高质量发展评价与实现路

服务业高质量发展日益成为经济高质量发展的重要题中之义。在充分梳理服务业高质量发展 文献的基础上,将服务业高质量发展解构为结构高质量、效益高质量、规模高质量、品牌高质量4 个部分, 进而构建了服务业高质量发展的评价指标体系。根据该指标体系对中国服务业高质量发展进行总体、分 类、分区测算,发现中国服务业高质量发展呈现总体上升、品牌迟滞、区域失调的态势。研究发现:中国服 务业可以通过结构优化、品牌再造、融合发展、协调共进四个路径来实现更优的高质量发展。本文的研究 是建构服务业高质量发展指标评价的有益尝试,对服务业高质量发展具有一定的政策启示。     

Corporate Management,Industry Competition and the Sustainability of Firm Abnormal Profitability

This paper models the sustainability of firmabnormal profitability and uses theeffectiveness of corporate managementcapabilities as a test to examine its impact onthe sustainability of firm abnormalprofitability. The role of industry competitionas a moderator between the effectiveness ofcorporate management capabilities and thesustainability of firm abnormal profitabilityis also examined. Consistent with theresource-based view of the firm, we found thatthe effectiveness of corporate managementcapabilities positively influence thesustainability of firm abnormal profitability.This implies that corporate managementcapabilities are important contributors to theentire bundle of firm-specific resources andcapabilities which enable some firms togenerate competitive advantages that aresustainable. The effectiveness of corporatemanagement capabilities has a larger influenceon the sustainability of firm abnormalprofitability for firms in lowly competitive ormonopolistic industries than firms in highlycompetitive industries. The findings supportthe notion that not only do firm capabilitiesyield sustainable competitive advantages andabnormal profitability, but also industrycompetition reinforces the impact of firmcapabilities in yielding sustainable abnormalprofitability.     

The Evolution of Knowledge and the Dynamics of an Industry Network

The paper moves a step forward in the direction of establishing a connection between the structure and evolution of knowledge bases and the structure and evolution of organizational forms in innovative activities in a science-intensive industry. The paper has an explicit focus on the dynamics of the network of collaborative agreements in R&D in the pharma/biotech industry after the “molecular biology revolution”. Using a comprehensive dataset, built by the authors integrating several sources in the industry, the dynamics of the network over time is extensively analyzed. With regards to network structure, it is found that, while the size of the network increases over time due to net flows of entry, its topological properties remain relatively unchanged. The evolution of the network has occurred without relevant deformations in the core-periphery profile. With regards to age-dependent propensity to collaborate, the paper finds that the extent of inter-generational collaboration is much more significant than intra-generational collaboration. In addition, the propensity of firms of a given generation to enter into collaboration with firms of a different generation increases with the distance between the two, while the total number of intra-generational collaborations decreases over time and, moreover, tends to decrease for most recent generations. In the paper a unitary and coherent explanation of the evidence is developed, coming to reveal the existence of a striking isomorphism between structural properties of the dynamics of knowledge and of the evolution of network structure.

“以农立国”还是“以工立国”？——民国时期立国之争的再思考

20世纪二三十年代,中国出现了一次关于“何以立国”的争论,争论的核心是“以工立国”还是“以农立国”。此次争论包括了耳熟能详的一些经济学家、哲学家、政治家等社会名流,以章士钊为代表的“守旧派”、梁漱溟、晏阳初等乡村建设运动者为代表的“改良派”和以董时进为代表的“创新派”坚持“以农立国”,他们的出发点是中国对于农国地位以及农国精神的维护;吴景超、张培刚、孙倬章则是“以工立国”派的重要拥趸,他们主要着眼于现实,提出只有建立强大的工业基础才能挽救民族于危亡之中。此外“非名流”乃至“草根”阶级也参与到了论战中,与他们相比,“名流”论战者有着更为宏观、全局性和深层次的把握。传统认为“工农之争”的论战以“以工立国”派的胜利而告终,然而从不同的视角看,“以农立国”的观点不无道理,甚至对于现阶段经济的发展仍有指导意义。     

不同规模农地抵押贷款可得性研究

以南阳市427户农户调查数据为样本,运用二元Logit回归模型对三类不同土地规模农户的农地抵押贷款可得性及其影响因素进行分析。结果发现,户主年龄、文化程度、家庭收入、房屋价值、社会资本、对贷款政策了解度及土地规模差异均对农户农地抵押贷款可得性具有显著影响。其中,家庭收入与房屋价值是影响不同土地规模农户农地抵押贷款可得性的共同因素,土地规模是影响农地抵押贷款可得性最为直接的关键性因素,随着土地规模增加,金融机构贷款审批更注重农户个人信用程度、社会资本和风险保障措施。     

我国制造业产能利用率测度与影响因素研究——基于十个重点行业

选取制造业的十个重点行业,使用2001-2014年的面板数据,运用数据包络分析法(DEA)对其产能利用率、技术效率和设备利用率进行了测算,结果显示:我国制造业的部分行业存在严重的产能过剩问题;非金属矿物制品业、黑色金属冶炼和压延加工业等传统行业的产能利用率较低;通信设备、计算机及其他电子设备制造业等新兴行业的产能利用率相对较高.剖析制造业产能过剩的影响因素,发现市场需求与产能利用率存在显著的正相关关系,资本密集度、就业水平、开放度、金融支持与产能利用率有显著的负相关关系.

中国建设“世界制造业强国”背景下的制造业技能人才研究

处于后工业化经济时代的当代世界,技能人才对推动国家经济的发展具有举足轻重的作用,因此,确保“质优量足”的技能人才成为制造业强国广泛关注的一个焦点,这加速造成了全球技能人才的激烈争夺,进而引发世界范围内大面积的“技能荒”现象.由此,文章在中国建设“世界制造业强国”的背景下,基于对制造业中心国家——英国、美国和日本制造业技能人才短缺现状和成因探讨的基础上,深入分析三国政府和企业采取的措施以及效果,以期为中国有效应对技能人才短缺提供参考.
