研究目的:深入探讨自然生态空间用途管制作用机理及管制策略,助力完善国土空间用途管制制度。研究方法:文献分析法、归纳演绎法。研究结果:(1)模型能够较好反映自然生态空间与城镇空间和农业空间的联动效应;(2)阐明了自然生态空间用途管制行为主体、空间利用行为主体、空间利用行为以及用途管制客体之间的关系及管制作用机理;(3)明确"生态底线"导向的直接用途管制与"精明增长"导向的间接用途管制方式并行的管制策略。研究结论:建议完善国土空间规划体系,建立自然生态空间管制实施机制,加强自然生态空间用途管制要与其他自然资源管理改革制度的统一设计,强化实施自然生态空间管控质量监测评估。     

How to improve the university–industry collaboration in Taiwan's animation industry? Academic vs. industrial perspectives

This study demonstrates the use of importance–performance analysis (IPA) to prioritise the motivators that can facilitate university–industry collaboration in the animation industry in Taiwan. This study confirms that financial supports and education are still major reasons for academia to participate in the university–industry collaboration. Reducing costs and obtaining human training are the reasons for animation firms to join the university–industry collaboration. However, by comparing the results of IPA for academia and industry, this study recommends four common interest motivators from both academic and industrial perspectives and where efforts should be concentrated. Research facilities, external competencies, talents, and innovation capacity are very important for the animation industry of Taiwan.     

经济新常态下我国粮食安全问题及发展研究

粮食安全关系着一个国家的社会稳定与民族的长远发展,是世界各国普遍关注的热点问题。我国属发展中国家,人口多耕地少,人地矛盾较为突出,粮食安全问题是国家需要长期关注的永久课题。保障粮食安全,对于经济新常态下我国的发展具有十分重要的意义。文章首先简要介绍了经济新常态的含义,然后运用比较分析、系统研究等方法深入分析我国粮食安全的现状,探明我国粮食安全所面临的主要问题。结果表明:我国粮食安全尽管目前基本有保障,但前景不容乐观。主要问题有生产成本上升,进口关税下降等,为探索保障未来我国粮食安全的途径,彻底解决我国的粮食安全所面临的问题,促进社会和谐发展提出建立粮食生产保护区,国家制定粮食最低收购价,增加科技投入,以合作社为龙头形成规模化生产经营,兴办国营企业,国家提供高质量生产资料等建议,旨在为党和政府制定相关方针政策提供有益参考。     

企业内部控制评价指标体系研究

通过对国内外内部控制研究文献的分析,从五要素即内部环境、风险评估、控制活动、信息与沟通及内部监督出发构建含5个一级指标21个二级指标的初始评价指标体系.然后通过探索性因子分析和验证性性因子分析对其可靠性及合理性进行检验,证明了该模型具有良好信度和效度等.最后将所构建的评价指标应用于同性质的企业并对其内部控制进行评价,结果验证所构建的企业内部控制指标体系的适用价值.

我国社会救助正当程序之实践及修正

社会救助正当程序是社会救助管理与服务中有助于实现社会救助公正结果，或与社会救助公正结果有关的程序。近年来，我国逐步建立了社会救助基本操作程序，包括社会救助标准制定与调整程序、家庭经济状况核查程序、社会救助申办程序等。然而，我国社会救助程序未得到足够的重视，现有的程序存在瑕疵，基层自由裁量权没有得到有效规制，没有建立回避、救助返还等制度。救助程序不完善，不利于保护申请人和救助对象的程序性权利，进而影响到他们的实体性权利，同时导致救助政策目标偏离，产生错保、漏保等现象。建议国家加快制定《社会救助法》，或单独制定《社会救助程序规则》，通过立法完善救助程序。     

Is it one break or ongoing permanent shocks that explains U.S. real GDP?

The relative importance of permanent versus cyclical shocks to GDP has been found to depend on the presence or absence of a single break in mean growth. We estimate unobserved components models conditional on a trend break having occurred in any specified quarter and use the Bayesian model averaging to combine the conditional estimates. We estimate a break occurred around 2006:1. Allowing for a break significantly reduces estimates of trend variance. However, enough spread remains in the posterior distribution to indicate that available data does not definitively settle the question of the relative importance of trend versus cycle.     

WHICH AGGLOMERATION EXTERNALITIES MATTER MOST AND WHY?

This paper revisits the ongoing discussion on the importance of agglomeration externalities – specifically specialization, diversity and competition effects – that may contribute to innovation, productivity and urban employment growth. Previous meta‐analyses suggested that the evidence on agglomeration externalities is strongly context‐specific. Expanding an earlier analysis of 31 articles, we seek to draw in this paper more robust conclusions by means of the statistical evidence for agglomeration externalities presented in 73 scientific articles, all building on the seminal work of Glaeser et al. (1992). Our results confirm that the heterogeneity among studies is huge and can only be partially accounted for by means of an ordered probit analysis. Additionally, some evidence of publication bias is found. We conclude that the conventional lines of inquiry in this literature may now have reached strongly diminishing returns. New lines of inquiry, using rich micro‐level data on firms and workers, dynamic general equilibrium models at the macro level, more attention for spatial and temporal variation in the impacts of agglomeration, and further investigations into the spatial scope of externalities are promising avenues for further research that can enhance our understanding of how agglomeration externalities continue to fuel our increasingly urbanized world.     

A LONGITUDINAL STUDY OF CHANGE IN THE ENGLISH NATIONAL HEALTH SERVICE

This paper reports the findings of a longitudinal comparative case study of three National Health Service (NHS) hospital Trusts in England, investigating the perceptions of clinical, managerial and accounting professionals towards changing cost accounting and performance measurement practices. It incorporates both qualitative and quantitative data analysis, and is based on a contextualist understanding of change management, utilising the content‐process‐context approach (Pettigrew and Lapsley, 1994) to investigate the influence of receptive versus non‐receptive contexts on change. The analysis reveals limited success in improving performance measurement practices (the content of change) in Trusts. Nevertheless the specific context within which change was operationalised was found to be very important, with central mangers playing a key role in influencing change. The process of change indicated slow shifts in clinical‐accountant‐managerial relations, partly driven by changes in financial flows within the organisations.     

Discrete time Wishart term structure models

This paper reveals that the class of Affine Term Structure Models (ATSMs) introduced by Duffie and Kan (1996) is larger than previously considered in the literature. In the framework of risk factors following a Wishart autoregressive process, we define the Wishart Term Structure Model (WTSM) as an extension of a subclass of Quadratic Term Structure Models (QTSMs), derive simple parameter restrictions that ensure positive bond yields at all maturities, and observe that the usual constraint on affine processes requiring that the volatility matrix be diagonal up to a path independent linear invertible transformation can be considerably relaxed.
