论我国政府主导型国企制度变迁深化的必然及约束   总被引:1,自引:0,他引:1  
政府主导型制度变迁是国有企业制度变迁的路径依赖之一,这是由客观的社会经济条件决定的。国企制度在同一轨迹上的变迁在取得巨大收益之后已进入边际效益递减、制度容量饱和的阶段,向更高效 水平的制度演进已成为必然。然而,政府主导型制度变迁也面临着政治竞争、交易费用、政治家效用函数、效率与稳定两难选择及其他体制性问题的约束。制度的进一步创新需要政治体制的相应调整、需要坚持政府主导型变迁方式,需要其他外部力量的影响。  相似文献

Using a method that avoids the need to specify earnings expectations, we demonstrate that the period surrounding the semi-annual announcement of Australian firms' earnings is, on average, an important source of information. Although there is substantial year-to-year variation, we observe no evidence of any significant time trend, and also conclude that a shift from Australian domestic generally accepted accounting principle to International Financial Reporting Standards did not impact the association between earnings announcement windows and stock returns. We also find no evidence that the informativeness of earnings announcements varies systematically with firm size, analyst following or economic news (i.e., positive vs. negative stock returns, profits vs. losses), although we do observe significant variation across industries. Our conclusion is further supported by contrasting the earnings release date with the days immediately prior to release, or high information days other than earnings announcement windows. Using a more precise event window relative to prior studies (i.e., 3 h vs. 3 days), we confirm that earnings announcements contain significant new information about fundamentals.  相似文献

以2011~2012年在国内 A 股市场上市的130家京津冀地区现代制造业上市公司为样本,通过Richardson 模型对样本投资效率进行评分,并用内容分析法对企业环境信息披露程度评分,以此研究京津冀地区现代制造业上市公司环境信息披露对企业投资效率的影响。研究结果显示:环境信息披露程度评分与公司投资效率评分存在正相关关系,但相关系数较低,这表明企业环境信息披露行为对企业投资效率影响较小,且不会使得企业投资效率降低。  相似文献

The increasing frequency and scope of financial crises have made global financial stability one of the major concerns of economic policy and decision makers. This has led to the understanding that financial and banking supervision has to be thought of as a systemic task, focusing on the interdependent relations among the institutions. Using network theory, we develop a dynamic model that uses a bipartite network of banks and their assets to analyze the system’s sensitivity to external shocks in individual asset classes and to evaluate the presence of features underlying the system that could lead to contagion. As a case study, we apply the model to stress test the Venezuelan banking system from 1998 to 2013. The introduced model was able to capture monthly changes in the structure of the system and the sensitivity of bank portfolios to different external shock scenarios and to identify systemic vulnerabilities and their time evolution. The model provides new tools for policy makers and supervision agencies to use for macroprudential dynamical stress testing.  相似文献

While the tourism sector shifts towards digital transformation, Destination Management Organisations (DMOs) often struggle to adapt to their changing technological environment. This study explores the antecedents of digital collaboration and develops a framework for micro-DMOs to enhance effective destination management through digital technologies. An integrated sequential qualitative approach was adopted by conducting multi-phase interviews, in addition to designing and trialling a real-world trial digital platform. The research provides empirical evidence that digital collaboration is essential for micro-DMOs, necessitating them to transform their current “websites” into digital platforms which act as a hub for business stakeholders to actively be involved in. Antecedents of successful digital collaboration include mutuality, trust, control, and leadership which may be manifested differently from non-digital collaboration. Additionally, the study identifies three aspects for digital collaboration; marketing, networking and knowledge sharing that demands specific attention. Our results have theoretical, methodological, and practical implications for academia, industry and policymakers.  相似文献

In 2017, the Chinese government implemented a national strategy of "Rural Vitalization" that sought to realize full-scale rural vitalization. However, is it possible to achieve vitalization for all the villages in China? How should their development potential be determined? This paper identified and analyzed the "element-composite" messages of rural development based on 99 exemplary sites of “Beautiful Villages” in China. Combined with the projection pursuit classification method, a diagnostic system of rural vitalization was established; then, Dehua County was taken as a case study for an in-depth analysis. Based on national data analysis, the final results indicated that livelihood resources (LR), agglomeration effects (AE), location and transportation (LT), cultural/natural landscapes (CN), and economic circumstance (EC) are essential elements for successful rural development. Additionally, EC was the only exogenous element, while the remaining elements were endogenous. Furthermore, the villages with better EC presented urbanization rates of 38∼82 % and Engel coefficients of 29∼41 % in their counties; exemplary sites lacking LR, CN, LT, and AE account for 13.13 %, 19.19 %, 26.26 %, and 60.61 % respectively, so the indispensability of these elements decreases progressively in sequence. Only 2 % of villages rely on single element for success, therefore, the composite pattern of development element was also critical; 10 out of 16 types were found to successfully facilitate village development, among which, the type of R-a-L-C (32.32 %) and R-A-L-C (15.15 %) were considered as the greatest potential patterns for vitalization. Finally, by means of the diagnostic system, the ratio of representative villages for high-low potential in Dehua County is evenly split; then, development paths, and land use policies that match with paths were proposed, on the basis of development potential and “element-composite” condition of themselves.  相似文献

On the basis of a liquidity management model, liquidity risks, defined as the probability of payment failures in a real-time gross settlement (RTGS) payment system, may either stem from liquidity management inefficiencies or insufficient cash balances. I will show that penalties charged on the amount of payment failures minimise liquidity risks without interfering with the bank’s technology preferences. I will instead show that liquidity requirements, although as effective as penalties to contain the risk of liquidity shortage, may distort the bank’s technology preferences and cannot stem liquidity management inefficiencies. I will also show that liquidity risks within RTGS payment systems are potentially smaller because they depend more on the liquidity management efficiency than on the randomness of cash inflows and outflows.  相似文献

无论从对自然环境的破坏程度还是污染程度来讲,农业都不亚于工业,在一些方面甚至超过工业,因此,治理农业污染,推行清洁生产,不仅是必要的,而且势在必行。在农业清洁生产过程中存在不完全信息的情况,这使生产者和消费者产生逆向选择,最终影响到农业清洁生产的发展。文章试图用信息经济学的理论分析农业清洁生产中的不完全信息问题,并提出了解决的建议。  相似文献
