区域创新、工业智能化与产业结构升级

本文构建了内生性区域创新能力的产出模型,对区域创新、工业智能化与产业结构升级三者之间的作用机理及空间效应进行理论分析,利用2006—2018年中国30个省份动态面板空间杜宾模型（PSDM）进行实证检验。研究结果表明：区域创新对产业结构升级具有显著的正向空间溢出效应,本地区创新水平的提升对邻近地区产业结构升级具有正向效应。另外,提升工业智能化水平能够有效促进区域创新对产业结构升级的正向激励效应,但这一激励效应存在地区异质性,即东部地区促进效果与全国层面保持一致,中部和西部地区不显著。     

基于"星形模型"的中小企业区域竞争力研究——关于中部六省的实际测算

中小企业竞争力作为区域竞争力提升中不可忽视的力量,已愈来愈受到人们的重视。文章以中小企业竞争力和区域竞争力理论为出发点,提出了中小企业区域竞争力概念,并在回顾波特国家钻石模型的基础上,提出了中小企业区域竞争力星形模型,同时将其应用于中部六省的中小企业区域竞争力的测算中,检验了模型的有效性和实用性。     

Minimum Quality Standards under Asymmetric Duopoly with Endogenous Quality Ordering: A Note

In this note, we revisit minimum quality standards (MQS) under a vertically differentiated duopoly. We generalize the model in Ronnen (1991) and Valletti (2000) by introducing asymmetry into the fixed cost of quality improvement and by explicitly taking into account the endogeneity of quality ordering. In the generalized model, we show that the results derived by Ronnen (1991) and Valletti (2000) are largely robust.     

Free Entry under Uncertainty

When focusing on firm’s risk-aversion in industry equilibrium, the number of firms may be either larger or smaller when comparing market equilibrium with and without price uncertainty. In this paper, we introduce risk-averse firms under cost uncertainty in a model of spatial differentiation and show that the impact of uncertainty will increase the number of firms in an industry. With increased uncertainty, the risk premium of the marginal buyer increases by more than the risk premium of the average buyer, so that the price increases by more than the risk premium. When turning to the free entry game, we find that the market generates too many firms.     

Effect of credible quality investment with Bertrand and Cournot competition

We show how credible revelation and ability to commit to quality choice effect equilibrium qualities and welfare when product market is either Bertrand or Cournot competition. We show that results depend on the type of competition but not generally on the cost of quality function. We show that with Bertrand competition, the equilibrium qualities are lower with credible commitment. Competition is moderated and producer surplus is higher and consumer surplus lower. With Cournot competition, higher quality will be better but lower quality will be worse with credible commitment. Consumer surplus is always greater with credible commitment and if cost does not increase too quickly with quality, producer surplus will also increase. Thus credible commitment is a collusive device with Bertrand competition but it can improve social welfare with Cournot competition.

城市地理学研究新的领域思考

改革开放以来，由于国民经济的迅速发展，我国工业化、城市化的进程明显加快。从国情分析可知，我国的城市化出现了五种特有的现象，这为城市地理学的研究提供了广阔的平台。城市地理学在我国城市发展与城市化的重大问题研究上，长期以来取得了许多重要成果，理论方法上也有重大建树，成为人文科学与自然科学研究领域中最为活跃的一支生力军^①。文章从我国实际出发，提出了城市地理学研究的思维方法及其若干新的研究领域。     

基于城市竞争力分析的城市定位——以青岛市为例

城市定位离不开区域条件的分析,但是区域分析不能仅局限于城市所在腹地,应根据需要在不同层次的区域进行综合比较。文章以青岛市为例,借助城市竞争力分析的框架,探讨了城市定位的定量化分析。根据地理学区域的思想,结合研究对象的行政地位和区位特点,从全国、东南沿海、山东省三种层次的区域分析了青岛市的城市地位和竞争力,指出了目前城市发展过程中的相对优势和不足,借此对青岛市进行了科学定位。     

区域经济发展中的形象塑造:以山西省为例

文章对区域形象塑造的必要性进行了分析,指出在注意力经济的时代背景下,区域形象塑造是欠发达地区实现跨越式发展的重要途径。在此基础上,对区域形象的概念和特点进行了辨析,从客观性与主观性、整体性与片面性、稳定性与可变性、现势性与前瞻性四个方面分析了区域形象塑造中需要注意的几个问题。以山西省为案例,论证了区域形象塑造在区域经济发展中的重要作用,指出山西省的区域形象经历了一个华夏文明的摇篮(古代)——商业金融中心(近代)——能源重化工基地(现代)——暴发户的乐土(未来可能)的历史嬗变过程,山西省要摆脱当前的形象危机,破解“资源的诅咒”,摆脱路径依赖,实现区域经济的持续发展,必须抛弃“能源重化工基地”的现有形象,塑造“节约山西”的区域新形象。     

西部地区金融发展的政策取向

在市场经济下,金融对于经济发展的作用至关重要,中国协调区域发展离不开金融的支持,实施区域金融政策是中国协调区域发展的现实选择。应尽快建立适应西部特点的新型金融组织体系,通过培育区域金融中心、健全区域金融协调机制,并在货币市场和资本市场实行有针对性的金融政策。     

论区域营销系统

区域营销实质上是一个战略市场管理过程,也是一个区域财富的增长过程。文章从区域营销系统的主客体和营销的目的出发,认为区域营销系统主要由四部分构成:主体子系统、目标市场及其决策过程、产品子系统、战略管理子系统。并认为营销实质上是一个社会管理过程,是一个产品和价值交换过程,而区域营销系统网络是实现区域产品和价值交换的平台。同时还认为区域形象是区域营销的产品包装。
