深基坑支护技术在房屋建筑施工中的运用策略试析

在我国经济实力不断增强的社会背景下,我国的建筑行业发展十分迅速,在数量、质量上,相较于以往都有了较大的突破.但在实际的施工过程中,由于我国高层建筑数量的逐渐增多,地基的深度逐渐增大,在施工中如果对相关的施工技术没有进行一定的选择,就会对人们后期的使用产生较大的威胁.深基坑支护技术的迅速发展和广泛应用不仅在于它们能够促进我国建筑项目工程施工的有序性和顺利进行,也能充分满足实际的施工服务所需,从而保证我国建筑项目工程的施工整体设计施工服务质量,促进我国建筑工程行业的快速健康稳定发展.     

Corporate Lobbying and Firm Performance

Corporate lobbying activities are designed to influence legislators, regulators and courts, presumably to encourage favorable policies and/or outcomes. In dollar terms, corporate lobbying expenditures are typically one or even two orders of magnitude larger than spending by Political Action Committees (PAC), and, unlike PAC donations, lobbying amounts are direct corporate expenditures. We use data made available by the Lobbying Disclosure Act of 1995 to examine this more pervasive form of corporate political activity. We find that, on average, lobbying is positively related to accounting and market measures of financial performance. These results are robust across a number of empirical specifications. We also report market performance evidence using a portfolio approach. We find that portfolios of firms with the highest lobbying intensities significantly outperform their benchmarks in the three years following portfolio formation.     

加强政策事中事后评估的思考

党的十九届四中全会明确提出要强化决策执行、评估、监督,做好政策评估对优化政府职能、推动国家治理体系和能力现代化有积极作用。加强政策运行情况的评估,应从优化评估工作机制、完善和培育评估机构、强化评估结果的应用入手,不断提升评估工作质量,形成适应中国特色社会主义现代化治理体系的事中事后政策评估机制。     

More on Middlemen: Equilibrium Entry and Efficiency in Intermediated Markets

This paper generalizes Rubinstein and Wolinsky's (1987) model of middlemen (intermediation) by incorporating production and search costs, plus more general matching and bargaining. This allows us to study many new issues, including entry, efficiency, and dynamics. In the benchmark model, equilibrium exists uniquely and involves production and intermediation for some parameters but not others. Sometimes intermediation is essential: the market operates if and only if middlemen are active. If bargaining powers are set correctly equilibrium is efficient; if not there can be too much or too little economic activity. This is novel, compared to the original Rubinstein–Wolinsky model, where equilibrium is always efficient.     

对驰名商标“异化”的另一种认识

驰名商标的异化不仅指认定过程中的反常现象,还包括使用过程中的反常现象。用另一种眼光看,驰名商标的异化并非总是有害的,它还有促进商标法制建设、推动品牌的创造及其价值的发挥、营造良好的品牌文化等积极功能。因此,对驰名商标的异化现象应当区别对待,容忍具有较强正当性的异化现象,对于危害较大的异化现象则应采取多种措施予以消除。     

Does the Quality of Corporate Governance Affect Firm Valuation and Risk? Evidence from a Corporate Governance Scorecard in Hong Kong*

Using Hong Kong firm data, we construct an index of corporate governance during 2002–2005, which scores the corporate governance practices of listed companies from the public shareholders' perspective based on the Organization for Economic Corporation and Development Principles of Corporate Governance. The findings show that family firms and firms with concentrated ownership structures are associated with bad corporate governance. The evidence also shows that these firms improve their corporate governance practices slower than their peers. Overall, the quality of corporate governance is very significant in explaining future company stock returns and risk. Good corporate governance is associated with both higher stock returns and with lower risk. Improvements in corporate governance are associated with significantly higher stock returns and lower company risk.     

ON‐THE‐JOB SEARCH,PRODUCTIVITY SHOCKS,AND THE INDIVIDUAL EARNINGS PROCESS*

Individual labor earnings observed in worker panel data have complex, highly persistent dynamics. We investigate the capacity of a structural job search model with on‐the‐job search, wage renegotiation by mutual consent, and i.i.d. productivity shocks to replicate salient properties of these dynamics, such as the covariance structure of earnings, the evolution of individual earnings mean, and variance with the duration of uninterrupted employment, or the distribution of year‐to‐year earnings changes. Structural estimation of our model on a 12‐year panel of highly educated British workers shows that our simple framework produces a dynamic earnings structure that is remarkably consistent with the data.
