金融产业集聚在地区工业化进程中发挥着非常重要的作用。通过区位商法的分析发现,我国东、中、西部地区金融产业的集聚程度有着较大差距,其中东部地区集聚度较高,而中西部地区则集聚度较低。面板数据的计量检验结果表明,金融产业空间集聚的差异对我国三大不同地区工业化产生了不同影响。总体而言,银行业集聚对工业化的影响作用最大,而证券和保险业集聚作用则较小,而对于不同地区、不同省份以及不同时期来说,这一作用也存在着差异。因此,可以通过调整金融业的空间集聚格局来促进工业化的发展。 相似文献

通过分析2008-2012年A股上市公司相关数据,研究会计师事务所转制对于审计质量的影响,结果显示:特殊普通合伙制会计师事务所的审计质量高于有限责任制会计师事务所的审计质量;转制后会计师事务所的审计质量高于转制前会计师事务所的审计质量,但是转制对审计质量的提高有一定的不同步性。研究结论为转制政策的合理性提供了证据支撑,也为其他中小型会计师事务所改制提供了必要性方面的经验依据。 相似文献

Many studies examine firm private knowledge, but purport to be generalizable to the totality of firm knowledge, both public and private. This study demonstrates that public and private firm knowledge are empirically separable constructs that have significant and yet different influences on innovative outcomes. The example of product development effectiveness within this study shows that both public and private knowledge are significantly related to product development quality; however, public knowledge is negatively related to quality lapses while private knowledge is positively related to quality lapses.

Advances in the study of both markets and platforms contribute to economics. Platforms are typically digital markets, although platforms can designate markets generally. So, the economics of markets and the economics of platforms are one and the same. Platforms show the critical role of intermediaries in endogenous price adjustment and market clearing. The platform model remedies problems with general equilibrium analysis by combining and extending the basic Walrasian and Marshalian market models. The analysis of platforms provides explanations for the bid–ask spread, including market power, search costs, matching costs, adverse selection, and moral hazard. The study of platforms demonstrates the importance of participation and coordination in the formation of markets. The discussion emphasizes that platforms have significant implications for the theory of the firm. The analysis further considers how platforms affect innovation and entrepreneurship. 相似文献

This paper focuses on an emissions permit market dominated by one firm and with a government concerned about social efficiency and permits revenue. In this setting, it is shown that the dominant firm's market power reduces the opportunities for the government to raise non-distortionary revenue from permits without loss of consumer surplus. Since the government's objectives are thus hampered in auctioning permits, the dominant firm should be excluded from the auction. Specifically, the regulator should sell permits directly, through bilateral negotiation, to the dominant firm, and auction off the remaining permits to the fringe firms. 相似文献

This paper makes comparative statics in a model in which oligopolistic and monopolistically competitive firms that are heterogeneous in productivity compete. We demonstrate that (i) entry of oligopolistic incumbents, (ii) reduction in entry cost of monopolistically competitive entrants, and (iii) market size expansion improve the average productivity in the whole economy. However, (i) and (iii) raise welfare, but (ii) may lower welfare because of the presence of oligopolistic firms. 相似文献

ABSTRACT Firm innovation is embedded in a collaboration network among researchers and a knowledge network composed of knowledge elements; the two networks are decoupled. Guided by social network theory, this study puts forward the definition and the classification of firm dual network structure, probes into the influence of dual network structure on firm performance, and explores the alignment between innovation strategy and firm dual network structure. We conduct an empirical study of 183 listed companies in China from 2004 to 2018. It is found that the four types of dual network structure all have positive impacts on firm performance, and the impact of a collaboration network is slightly higher than that of a knowledge network. Besides, innovation strategy plays a positive moderating role in the relationship between dual network structure and firm performance. Our findings provide new ideas for firms to identify and optimise knowledge and collaboration network structures and match them with innovation strategy to improve performance. 相似文献

替代、互补及互嵌:企业与市场关系的新考察 总被引:1,自引:0,他引:1
在现实世界中,企业市场关系呈现出替代、互补及互嵌等多种特征,使得单一的“替代”说或“互补”论均缺乏足够的解释力。本文从交易费用角度将交易关系分为三种类型并指出企业和市场谁更有利于交易费用的节约,主要取决于交易品的特征以及交易本身的具体职能。企业其实是一种通过非人力资本和人力资本、人力资本和人力资本间相互交易以实现生产功能的特殊履约机制。这样就不难理解,只有部分交易可以通过企业与市场间的相互替代来提高效率,而更多的交易则须通过改善企业内部管理或改进市场制度本身来提高其效率。 相似文献

We propose a general theory of innovation that illustrates the relative benefits of performing process versus product R&D when firm size is endogenous. A firm's size, scope, and R&D portfolio are shown to reflect the same underlying characteristic of the firm, namely manufacturing efficiency. We demonstrate that efficient firms become larger, have greater scope, and perform more of both process and product R&D. In light of decreasing returns to R&D, this implies small firms obtain more product innovations per dollar of R&D than large firms, which is consistent with evidence we present that small firms are more innovative than large firms as they obtain more patent counts and citations per dollar of R&D. 相似文献
