产业技术创新战略联盟：研发战略联盟的产业拓展

产业技术创新战略联盟是以企业为主体、以市场为导向、以利益为纽带的新型技术创新组织形态,是研发战略联盟在产业层面的拓展。文章从战略联盟理论出发,分析产业技术创新战略联盟的特征和使命,并提出构建其应注意的几个战略问题：突出产业技术创新战略联盟的产业特征;注意构建产业技术创新战略联盟网络中的战略金三角;选择合理的产业技术创新战略联盟的运行模式;构建联盟成果的分享机制和联盟风险分担机制。     

美国农地开发规模化的经济分析及启示

全面理解农地开发规模化的思想,突破传统的以片面扩大农地耕种面积为增收目标的外扩规模型,或以单纯提高小块土地面积上生产要素追加量的内增规模型开发的观念是极端重要的。通过对美国农地开发规模化的实证研究,认为美国农地开发是立足国内资源,通过技术创新,克服资源约束,将以机械技术为特点的农地外扩规模开发与生物良种技术为标志的内含规模开发很好结合的成功典范,这无疑对我国当前农村如何在坚持家庭联产承包经营责任制的基础上,通过制度创新,实施适度的农地开发规模经营,进一步释放农户家庭在经营规模上的内在潜能、增加农户收入具有极其重要的借鉴意义。     

产能过剩化解对策——国企盲目投资扩张诱因分析

相关数据显示,以国企投资为主的传统制造业产能过剩情况严重,国有企业也是产能过剩率先爆发的“重灾区”。探究国企投资冲动背后的深层次诱因,可归结为内部成本的外部化和国企产权不明晰两大原因。化解产能过剩必须建立起长效化解机制,一方面通过完善市场竞争机制来还原市场对资源配置的决定性作用,另一方面通过实质性地推进国企改革,来最终达到根治产能过剩的目的。     

Do health system reforms stand a chance?

While most major reforms of health systems fail, those that succeed are motivated by politicians' quest for reducing the health burden on their budget in response to a shift in voters' preferences away from public health. An Edgeworth box is used to depict their preferences, in addition to those of (potential) patients and health‐care providers. Politicians are found to severely constrain the area of mutual advantage, suggesting that only minor reforms are possible unless they promise to lower health‐care expenditure. An efficiency‐enhancing change that would enlarge the box and hence the area of mutual advantage would be to suppress the requirement imposed on health insurers to purchase domestically, rather than being free to directly import health‐care services and drugs.     

论股东代表诉讼之判决既判力主观范围的扩张

股东代表诉讼判决既判力主观范围的扩张，包括向公司与其他股东二者的扩张。长期以来原告股东与公司的关系存在诉讼代理与诉讼担当之争，综合立法现状、制度渊源与改革成本等因素的考量，原告股东与公司的关系应定性为法定诉讼担当，从而为判决既判力向公司扩张提供正当理论支撑。但受制于股东代表诉讼前置程序形骸化，对原告股东起诉的正当性审查无从实现，公司与其他股东对于诉讼的获悉存在信息壁垒，由此应当通过诉讼告知程序为公司或其他股东作为有独立请求权第三人进入诉讼开辟通路。同时借由不起诉理由书与统一案件受理费等程序构建，作为其他股东进入诉讼的激励机制，进而为既判力的扩张提供有理性基础。     

The COVID-19 crisis: A public choice view

Many observers have been puzzled by the sight of otherwise freedom-loving citizens consenting to the stripping of their civil rights and the massive budgetary expansion of their governments in response to the COVID-19 pandemic. Conversely, governments who ‘kept their cool’ such as those of Brazil and Sweden were heavily criticised by the Western media. Adopting James Buchanan's contractarian approach, this article seeks to model how the interplay between citizens and their government is affected by a health crisis. Citizens' increased willingness to pay for improved control of risks is found to play a major role.     

Enhanced network effects and stochastic modelling in generation expansion planning: Insights from an insular power system

Electricity generation capacity expansion is driven by both economic and socio-political realities. Policy makers determine public infrastructural decisions, such as climate and renewable targets, and transmission infrastructure, and the optimal generation capacity expansion follows. Policy makers therefore require planning models that can determine the optimal generation capacity mix in the long run under various scenarios, including policy choices. This work presents a planning model based on linearised alternating current optimal power flow which determines optimal generation capacity expansion and operation, in a least-cost manner, given global and local technical constraints, as well as policy decisions. We apply the model to a test case of the island of Ireland, which has two weakly interconnected systems, high renewable generation targets and low storage and interconnection. We determine the optimal generation expansion and operation out to 2030 considering the effects of increased multi-area interconnection, existing fossil fuel generation phase-out and increased renewable generation targets and carbon prices. Our results find that costs and emissions are driven primarily by the decommissioning of old inefficient generation units. High renewable targets, on the other hand, render increased carbon prices relatively ineffective in reducing system emissions. Furthermore, high renewable generation targets crowd out low-carbon power generation options such as carbon capture and storage (CCS). The strategic north-south interconnection has little effect on renewable energy source installations required to achieve renewable power generation targets but does impact on security of supply and the congestion level across the island.     

Bartlett correction to the likelihood ratio test for MCAR with two‐step monotone sample

Assuming that two‐step monotone missing data is drawn from a multivariate normal population, this paper derives the Bartlett‐type correction to the likelihood ratio test for missing completely at random (MCAR), which plays an important role in the statistical analysis of incomplete datasets. The advantages of our approach are confirmed in Monte Carlo simulations. Our correction drastically improved the accuracy of the type I error in Little's (1988, Journal of the American Statistical Association, 83 , 1198–1202) test for MCAR and performed well even on moderate sample sizes.     

The Effectiveness of Fiscal Policy Over the Business Cycle: A CEE Perspective

In this article we analyze the effectiveness of fiscal policy—for a group of four Central and Eastern European countries. The recent literature shows that fiscal multipliers in the developed economies are higher during recession than expansion. So far, similar empirical analyses have been lacking for CEE countries. The results presented in this article show that fiscal multipliers in CEE countries differ with respect to the phase of the business cycle. Based on the SVAR methodology in which we allow for deterministic regime switching, we show that the government spending multipliers are significantly higher when the output gap is negative.
