德国租借时期的青岛园林在中国近代园林中独树一帜,是世界范围的造林典范,是从造林到造园的成功探索,城市层面的建设意义突出。以史志、老照片、规划图与建设状况图等史实为依据,结合现场调研,梳理青岛园林规划,揭示其城市设计、科学生态、林业生产以及经济实用的规划思想。考证出公园、绿地以及林荫道布局在城市重要功能区;这些公园绿地既受到德国近代思潮的影响,又在地域环境中追求自然之美与森林化景观效果。希望理清青岛德国租借时期园林建设的状况,对当前我国城乡园林建设有所启发。 相似文献

Employing a sample of 2,957 operational‐risk events across 31 countries from 1990 to 2011, we find that financial institutions located in countries with higher individualism tend to have higher operational risk. This positive relation is achieved through the risk‐taking channel and the earnings‐management channel. In addition, the magnitude of operational losses is higher in more individualistic countries. The results suggest that individualism serves as an important informal institutional determinant of operational risk in an international context. Endogeneity tests and various robustness checks confirm our findings. 相似文献

Some labour contract negotiations involve strikes while most conclude with immediate settlement. This article offers a model of union‐firm negotiation with private information to show that either strikes or immediate settlement will take place in the equilibrium. Different from most signalling literature where the signals are exogenously given, this article endogenizes the choice of signals. We compare two signals, the employment level and the strategic delay. We show that the low‐revenue firm will choose the signal which gives it higher payoff while separating itself from the high‐revenue firm. 相似文献

In a small, open and resource-poor economy, import and export dependency have an ever-growing impact on local policy decisions, which makes local (environmental) policy-makers increasingly depend on global data. This increases the interest in models that link local production and consumption data to global production, trade and environmental data. The recent increase in availability of global environmentally extended multi-regional input-output tables (EE-MRIO tables) provides an opportunity to link them with existing local environmentally extended input-output tables (EE-RIO tables). These combined tables make it possible (1) to analyse the links between local and global production and consumption and (2) to study global value chains, material use and environmental impacts simultaneously. However, estimations using input-output (I–O) analyses contain errors due to imperfect databases. In this article the magnitude of specification, aggregation and time errors are estimated and compared. The results show the need to combine local datasets with multi-regional ones and show that highest detailed (country and sector levels) as well as time series of I–O tables are the way forward for using I–O analyses in local policy-making. The paper provides guidance on trading off investments in model adoption and/or extension and the reliability of estimation results. 相似文献

A cynosure of the academic literature relating to initial public offerings (IPOs) is the question of why they are “mispriced” so frequently. The large and growing literature addressing this question is evidence as to its intractability. This paper develops a theory of underwriters’ behavior suggesting that they will exploit their private information to minimize the bilateral risks to themselves of firm-commitment IPOs. That minimization may cause them to knowingly underprice the issue. The main result in this paper is based, in part, on the premise that the random character of the investors’ demand for shares in the secondary market, given the spread, is governed by an estimable conditional probability distribution. The underwriters exploit their private knowledge of that probability distribution to influence the number of shares in the offering in such a way as to minimize their expected loss function. 相似文献

The problem of corruption in socio-economic development has long been a focus of academics and practitioners. To address this concern in China, the 18th National Congress of the Communist Party of China instituted a new anti-corruption policy. In this paper, we examine the impact of this recently enacted anti-corruption policy on the investment efficiency of subsidized enterprises from the perspective of government subsidies. We conclude that government subsidies have a significant positive impact on the overinvestment behavior of enterprises and that the anti-corruption work done by the government has effectively restrained the excessive investment behavior of government-subsidized enterprises. Further, we find that the anti-corruption policy is more effective in restricting overinvestment in subsidized state-owned enterprises than in non-state-owned enterprises. We examine the impact of the anti-corruption policy on excessive investment caused by government subsidies and enrich the body of research related to investment efficiency. We also provide empirical support for further research on the anti-corruption policy at the macro-market and micro-enterprise levels. The findings highlight the need to establish new cooperation between government and enterprises, to rationalize the distribution of administrative resources, and to promote the sustained and healthy development of the national economy. 相似文献
