In this paper, the executive of the 10th Five- Year Plan in the field of environmental protection and ecological constrution is reviewed, and the charactristics of economic growth and its environmental impact on the 11^th Five-Year Plan is forecasted and analyzed. A principal idea of eavironmental protection and ecological construction is put forward for the 11^th Five-Year Plan pertod: strensgthen the point treatment in key areas and set the main targets based on the idea. The relating countermeasures in national level are proposed as follows: set up appropriate ideas for official achievements by launching resources and environmental cost acconting; adjust the industrial struacture actively by industrial policies and strenuous work; develop circular economy, change the mode of environmental protecgon from end treatment to headstream and proeess control: strengthen the market mechanism in the process of pollution treatment, set up the system of "who treats who benefits" ; perfect interrelated laws and standards, strengthen the ability of environmental munagement; lay extra emphasis on two key targets: water pollution tretment in key river basins and management of the reserves; and combine the ecological consnuction and poverty alleviation in higher level. 相似文献

Within a continuous time life cycle model of consumption and savings, I study the properties of the most general class of additive intertemporal utility functionals. They are not necessarily stationary, and do not necessarily multiplicatively separate a discount factor from “per-period utility”. I prove rigorously that time consistency holds if and only if the per-period felicity function is multiplicatively separable in , the date of decision and in , the date of consumption, or equivalently, if the Fisherian instantaneous subjective discount rate does not depend on . The model allows to explain “anomalies in intertemporal choice” even when the agents are time consistent and various empirical regularities. On the other hand, the model allows to characterize mathematically the “effective consumption profile” of naive, time-inconsistent agents. 相似文献

Many institutions and governments grade academic journals for the evaluation of research. In this paper, we implement a multi-bibliometric methodology for the evaluation of such a list of journal grades. We examine the grades assigned by the Australian Business Deans Council (ABDC) for over 750 journals in the fields of economics and statistics. Firstly, we generate up to 48 bibliometric-based grades for each journal based on the grade distribution implied by the ABDC. Secondly, we categorize the bibliometrics employing a cluster analysis of an interrater agreement statistic. Thirdly, we present a visualization of the consistency of the grading by journal. Finally, we list those journals where the majority of the matched bibliometrics indicate a higher or lower grade than their ABDC grade. 相似文献

A large body of research shows that the migration of managers from one professional service firm to another weakens the old employer’s relationship with its clients, because migrating managers remove their relationship-specific knowledge and expertise – i.e., human and social capital – from their old employers, redeploying it to their new employers. This study extends this research by introducing a bi-directional perspective of social capital in which both firms and managers may exploit these relationship-specific resources. We use theory on social capital to build arguments about how one form of manager mobility, manager migration between two service providers in a single market, can both lead and lag the movement of client ties between those providers, and signaling theory to hypothesize the conditions under which this is likely to occur. Analyses using longitudinal data on New York City advertising agencies generally support our arguments. Our findings contribute to theory and research on manager migration, social capital, and signaling, and raise new questions for how the portability of relationship-specific social capital shapes markets. 相似文献

This paper provides the first evidence of algorithmic trading (AT) reducing liquidity in the Brazilian equities market. Our results are contrary to the majority of work which finds a positive relationship between AT and liquidity. Using the adoption of a new data center for the B3 exchange as an exogenous shock, we report evidence that AT increased realized spreads in both firm fixed-effects and vector autoregression estimates for 26 stocks between 2017 and 2018 using high-frequency data. We also provide evidence that AT increases commonality in liquidity, evidencing correlated transactions between automated traders. 相似文献

This brief exploratory empirical note seeks to identify key determinants of geographic differentials in the percentage growth rate of state-level employment in the US, with the primary focus being on the percentage net growth rate in the number of small firms (i.e., those with fewer than 20 employees) in each state, where this variable serves as a de facto reflection of ‘entrepreneurship’. In the interest of identifying other key factors that influence state-level employment growth rates, the effective income tax rate in each state, quality of life elements and labour market considerations are also included in the analysis. The study period runs from the year 2000 to the year 2007, ending just prior to the ‘Great Recession’. The estimation results imply that the state-level employment growth rate in the US was an increasing function of the percentage net growth rate in the number of small firms in each state. Thus, it appears that the small firms growth rate may in fact be a significant source. 相似文献

Cross-sectional data are compiled from the 2002, 2005, 2008 and 2012 World Bank Living Standards Measurement Study databases for Albania. Based on responses from 1169 firms, the entrepreneurs’ kinship networks are found to influence firm activity in a positive and negative way. The positive contribution occurs through employment, be it formal or informal. The persisting impact of the kinship networks fades away, and business and friendship networks have gained importance in recent years. 相似文献

将创业行为、知识溢出与产业集群发展绩效纳入一个研究框架,利用来自产业集群的310名创业者的调研数据,建立结构方程模型验证了三者关系的研究假设。结果表明:创业行为中的机会识别、资源整合、模仿行为对机会捕捉知识溢出和克服新进入缺陷知识溢出有正向影响;网络建构对两者的影响不显著;团队组建对机会捕捉知识溢出有正向影响,对克服新进入缺陷知识溢出的影响不显著;机会捕捉知识溢出对产业集群发展绩效中的产业关联和主体交互维度有正向影响,对集群创新维度的影响不显著;克服新进入缺陷知识溢出对产业关联、主体交互和集群创新均有正向影响。 相似文献
