美国银行关联交易监管演变考及借鉴

美国对银行业对外关联关系监管经历从“状态限制”到“行为限制”的发展过程,其理论基础是基于对银行独立市场判断能力的维护。我国应借鉴美国经验,加强对银行业关联交易的立法和外部监管,强化商业银行的内部控制;在监管中要兼顾效率和公平,加大对非公允关联交易的处罚力度,并赋予监管者一定的自由裁量权;不断修改、完善监管制度。

Wheat variety yield data: Do commercial and public performance tests provide the same information?

Wheat yields from reported performance test results are of economic importance to wheat producers, since their profits depend on selecting the optimal variety for their location. However, our data shows differences in absolute and relative wheat yields between commercial and public wheat breeding program's performance test data in Kansas. Newly available data are used to test if the difference in yields arose from potential selectivity bias, and to determine the contribution of private and public wheat breeding programs to varietal yield improvement during 2007–2012. Both Heckman selection models and multiple regression showed no statistical evidence of the potential presence of selectivity bias rather, managerial practices, agronomic conditions, field location, and inherent genetic traits of the seed variety were identify as the source of yield differences.     

Remittance,Institutions and Investment Volatility Interactions: An Intercontinental Analysis

Generating massive investment for growth and development has been one of the main policy goals of most economies around the globe. Countries, most especially developing ones, are highly susceptible to investment volatility owing largely to the fragile nature of their economies as well as weaknesses in terms of dysfunctional institutions. Therefore, sound economic management suggests the need to better understand possible sources for mitigating the adverse effects of investment volatility. Remittances have been identified as important capital flows which do a good job of dousing macroeconomic volatilities. It is on this basis that the study sought to uncover the causal relationship between remittances and investment volatility via the intermediating role of institutions. Using a panel of 70 countries and the system Generalized Method of Moments (GMM) estimator, three insightful outcomes come to the fore. First, remittances played countercyclical roles across the estimated regressions. Second, institutional quality had no significant role in mitigating investment volatility and lastly, the interactive terms of both remittances and institutions significantly mitigated the negative impacts of investment volatility with the exception of the political component of the institutional architecture. Policy suggestions are drawn based on our results.     

创业企业何以提高创新绩效——基于创业学习与商业模式创新协同联动视角的QCA方法

以150个创业企业为样本，基于创业学习和商业模式创新理论，运用模糊集定性比较分析方法（fsQCA），探究经验学习、认知学习、新颖型商业模式创新和效率型商业模式创新对创新绩效的影响路径及机制。研究发现，存在新颖型商业模式创新等4条创新绩效产出关键路径；相较于效率型商业模式创新，新颖型商业模式创新在关键路径中更容易提高创新绩效；利用QCA方法证实了影响创业企业创新绩效的组态内部各要素之间的替代性。结论丰富了创新绩效产出内部机制，可为创业企业提高创新绩效提供指导和借鉴。     

中国省域科技特派员制度实施绩效评估

2016年5月《国务院办公厅关于深入推行科技特派员制度的若干意见》发布实施，但其实施效果如何有待验证。构建科技特派员制度实施绩效评估指标体系，利用改进熵值法和官方统计数据，对中国省域科技特派员制度实施绩效进行实证评估，并对评估结果进行聚类分析。结果表明，中国大多数省份科技特派员制度实施绩效水平较低；根据实施科技开发项目、形成利益共同体、服务农民情况、推广服务和扶贫成效5个绩效评估维度，可以将中国内地31个省份划分为5种类型；即使是总绩效水平较高的地区，在科技特派员制度实施绩效方面也存在一些短板。     

国家级新区绿色增长能力建设影响因素分析

基于利益相关者理论，通过文献研究与实地调研，梳理了影响国家级新区绿色增长能力建设的主要因素，并应用Grey DEMATEL方法进行影响因素因果关系分析，在此基础上进一步剖析国家级新区绿色增长能力建设内在机理。研究结果表明：法律法规完善性是影响国家级新区绿色增长能力建设的根本性动力因素，同时，也是新区绿色增长能力建设内在机理的重要外在驱动力。此外，当地居民环境意识也是影响国家级新区绿色增长能力建设的重要结果性因素，而企业绿色管理实践、绿色技术进步与创新能力作为重要的关键性因素，对国家级新区绿色增长能力作用显著，是国家级新区绿色增长能力建设的重要内在驱动力。     

How much do alternative cookstoves reduce biomass fuel use? Evidence from North India

Despite widespread global efforts to promote clean cookstoves to achieve improvements in air and forest quality, and to reduce global climate change, surprisingly little is known about the degree to which these actually reduce biomass fuel consumption in real-world settings. Using data from in-house weighing of fuel conducted in rural India, we examine the impact of cleaner cookstoves ⿿ most of which are LPG stoves ⿿ on three key outcomes related to solid fuel use. Our results suggest that using a clean cookstove is associated with daily reductions of about 4.5 kg of biomass fuel, 160 fewer minutes cooking on traditional stoves, and 105 fewer minutes collecting biomass fuels. These findings of substantial savings are robust to the use of estimators with varying levels of control for selection, and to alternative data obtained from household self-reports. Our results support the idea that efforts to promote clean stoves among poor rural households can reduce solid fuel use and cooking time, and that rebound effects toward greater amounts of cooking on multiple stoves are not sufficient to eliminate these gains. We also find, however, that households who have greater wealth, fewer members, are in less marginalized groups, and practice other health-averting behaviors, are more likely to use these cleaner stoves, which suggests that socio-economic status plays an important role in determining who benefits from such technologies. Future efforts to capture social benefits must therefore consider how to promote the use of alternative technologies by poor households, given that these households are least likely to own clean stoves.
