地方政府经济竞争下的企业负担——来自上市公司的经验证据

本文基于分权体制下政企之间的两阶段动态博弈模型以及在此基础上构建的计量模型,将地级市之间经济竞争程度与A股非金融类上市公司数据相匹配,验证了地方政府经济竞争程度与企业实际税负之间的关系。研究结果表明,当地方政府所面临的经济竞争程度越激烈时,其辖区内上市公司的实际税负越低。进一步分析发现,地方政府经济竞争对辖区企业的减税效应存在显著的地区、产业和所有制异质性;分位数回归发现,辖区企业处于不同税负强度时,地方政府经济竞争的减税效应也存在明显差异。在当前减税降费、让利于企的新时代背景下,本文的研究对落实减税降费政策和规范横向竞争中地方政府行为具有启示意义。     

人力资本与社会资本视角的西安农民工城市融入实证研究

通过建立模型,对人力资本、社会资本与农民工城市融入的关系进行多元回归分析。分析表明,农民工人力资本中的文化程度、技能培训和健康状况与农民工城市融入呈显著正相关,以农民工寻找工作时间、交往范围和参加社会组织情况为代表的社会资本对农民工城市融入有着显著影响。为促进进一步城市融入的实现,政府与社会均应积极采取有效措施,充分提升农民工的人力资本和丰富其社会资本,加快我国城市化的健康发展与新型城镇化战略的推进落实。     

The Significance of Credit Rationing on Real Investment Activity – A Test for the Significance of Capital-Market Imperfection in Japan

Does bank credit matter to the real investment finance of firms? If so, to what kind of firms does it matter, and why? Despite the progress of research in this field, there is still little empirical consensus on these problems. This paper contributes to the understanding of capital-market imperfection in Japan by answering these questions. I introduce new methods to test the significance of credit rationing and show that bank credit is indeed a very important determinant of real investment activity of small firms. The availability of long-term loans has particularly significant effects on the investment opportunities of small firms, although large firms with capital of more than 1 billion yen are free from credit rationing.

Some general results for moments in bivariate distributions

The purpose of this paper is to present a closed formula to compute the moments of a general function from the knowledge of its bivariate survival function. The result is derived by utilizing an integration by parts formula for two variables, which is not readily available in the literature. Many of the existing results are obtained as special cases. Finally, two examples are presented to illustrate the results. In both the examples, mixed moments as well as moments for the series system and parallel system are obtained. The integration by parts formula in two variables, derived here, is of interest in its own right and we hope that it will be useful in other investigations. The integration by parts formula in two variables is derived as a special case of a general formula in n variables.

Balancing centripetal and centrifugal forces in the entrepreneurial university: a study of 10 research centres in a technical university

In the recent interest for the so-called entrepreneurial university, there is a strong emphasis on academic (i.e. theoretical) knowledge to be used more effectively as a source of innovation and renewal in industry. Drawing on a theoretical framework developed by the literature theorist Mikhail Bakhtin and a study of 10 research centres in a major technical university, this paper suggests that rather than representing something radically new, the entrepreneurial university is a domain wherein traditional academic research interests and industry objectives are continuously negotiated and mutually adjusted. Seen in this view, the entrepreneurial university is what is always in a process of becoming, in flux and change, continuously under the influence of opposing and complementary goals and objectives. Therefore, the entrepreneurial university is not a solid state or an entrenched position but the effect of an attitude towards the role and purpose of the university in the so-called knowledge society.
