Production subcontracting and location

Using data from a panel of Spanish manufacturing firms, I examine factors that explain firms' production subcontracting decisions and test whether there is any evidence that production subcontracting is facilitated in areas typically associated with higher agglomeration economies. The results show that location matters. Firms in industry agglomerations are more likely to subcontract production activities. While in general, larger and older firms as well as high wage firms show a greater probability for production subcontracting, industry agglomeration particularly facilitates subcontracting for smaller and lower wage firms and it allows firms to respond to a greater degree to expansive demand conditions by taking advantage of subcontracting.     

人口集聚能促进区域技术创新吗

基于2005-2014年中国省级面板数据,使用固定效应、随机效应和系统广义矩估计方法,通过区分一般人口集聚和人才集聚两个指标,研究了人口集聚对区域技术创新的影响,并分析了不同区域之间两者关系的异同。研究结果表明：一般人口集聚和区域技术创新之间呈“正U型关系”,同时人才集聚显著促进了区域技术创新。在不同区域层面,一般人口集聚在东部和西部地区均存在“正U型”关系,且对于西部地区技术创新的作用比东部地区更大,但在中部地区,两者关系并未呈现“U型”关系,而是呈持续负向影响。此外,相比东部地区,人才集聚对于中部和西部地区技术创新的作用更强。     

科技人才区域集聚为何不同 ——基于创新环境空间差异的解释

我国科技人才集聚具有地区差异性,并且与创新环境表现出明显的空间同位与同向演化特征,因此,从创新环境空间差异这一角度解释科技人才在区域集聚上的不同具有合理性。利用2010-2019年中国内地31个省（市、区）面板数据,通过构建空间杜宾模型考察区域创新环境对科技人才集聚的影响。结果表明：在全国总样本下,良好的区域创新环境显著促进本地区科技人才集聚,并对周围地区产生虹吸效应;在分样本情境下,地区创新环境对科技人才集聚的影响具有空间异质性,在东、中、西部地区,创新环境均对本地科技人才集聚产生不同程度的促进作用,其中,东部和中部地区创新环境的本地科技人才集聚作用最显著,西部地区相对较弱,同时,东部地区创新环境对邻近地区科技人才集聚具有显著虹吸效应,而中部地区和西部地区未有体现。据此,针对不同区域提出不同创新环境改善建议,以促进科技人才集聚。     

产品市场竞争、领导权结构与公司多元化战略

通过解释领导权结构与公司多元化战略之间的对立结果,明确了代理理论与管家理论各自的适用范围,探讨了领导权结构与多元化战略两者的关系如何随着产品市场竞争程度的不同而变化。将产品市场竞争引入到研究中,对于如何依据不同情境选择最合适的制度设计提供了很好的分析思路。     

中外城市群发展经验及其对山东半岛城市群的启示

城市群(带)是在工业化基础上而产生的一种城市高级化的空间组织形式,是区域参与国际竞争的战略支点。本文从解析城市群(带)研究的相关理论入手,着重分析了中外城市群发展的一般特征和形成的经验,提出了良好的区位和基础设施是城市群(带)发展的条件,工业化是其动力,产业转移是其发展的机遇,产业联系是其成功的关键。并以此为基础,对山东半岛建设城市群的路径和措施进行了对比分析,提出了对策建议。     

最终控制人与多元化价值效果——基于上市公司平衡面板数据的检验

众多研究表明,多元化对企业价值有显著影响,但是多元化究竟是增加了企业的价值还是减少了企业的价值则没有一致的结论。本文通过对2001至2004年我国上市公司的平衡面板数据进行分析后发现,多元化显著增加了上市公司的企业价值。无论是中央控股的国有上市公司还是地方控股的国有上市公司,均存在溢价现象,中央控股公司的多元化溢价的程度,显著大于地方控股公司的多元化溢价程度。而民营控股公司的多元化行为对企业价值没有显著影响。     

Portfolio selection, diversification and fund-of-funds: a note

The present paper examines the performance and diversification properties of active Australian equity fund‐of‐funds (FoF). Simulation analysis is employed to examine portfolio performance as a function of the number of funds in the portfolio. The present paper finds that as the number of funds in an FoF portfolio increases, performance improves in a mean–variance setting; however, measures of skewness and kurtosis behave less favourably given an investor's preferences for the higher moments of the return distribution. The majority of diversification benefits are realized when a portfolio of approximately 6 active equity funds are included in the FoF portfolio.     

The Evolution of Co‐operation,Pairings and Networks

In this paper we develop an approach that may be helpful in analysing a variety of issues related to the evolution of corporate activity. We analyse the firm as an integrated system concerned with the management and organisation of internal and external linkages between businesses, with the emergence of co‐operative behaviour as an endogenous feature of growing systems. It is argued that such a perspective can help illuminate a number of topics relating to the theory of the firm, including its boundaries and the mode of co‐ordination of economic activity, particularly the choice between integration and co‐operative modes of operation.     

Public Procurement and Foreign Direct Investment Across France,Germany, Italy and the UK

Foreign direct investment (FDI) has become an important factor of economic development during the last decades. FDI contributes to the economic growth of the host economy through learning, diffusion of technology, positive externalities and capital inflows. Attracting FDI is currently an objective in its own right for many countries and this paper aims to identify policies affecting the multinational firm’s decision to establish a subsidiary. After accounting for labour productivity and trade openness, cross-section analysis, both industry-wise and country-wise, indicates that public procurement, especially “buy national” policies, and agglomeration economies are statistically significant determinants of FDI. Although our findings pertain to four large European economies, e.g. France, Germany, Italy and the UK, they constitute relevant policy guidelines for developing countries as well.      

地区差距、产业聚集与经济增长:理论及来自广东省的证据

中国经济的高速增长和地区差距的不断拉大已经成为不可回避的现实问题。从现有文献看,以新古典框架来解释地区差距及其原因是目前我国学者采用的主要理论和方法。本文以新经济地理学理论为主要框架,从产业聚集与扩散的变化来研究由此而导致的经济增长效率的不同和地区差距的变化;并以广东省为案例,运用具体指标和Granger因果检验技术,从经验上证实了核心区域的产业聚集对整个广东省经济增长的拉动效应要明显强于边缘区域,同时也导致了地区差距的扩大。
