Environmental non-compliance is affected by the decentralized shaping of environmental policy by local governments and enforcement actions by public bodies. Illegal waste disposal is examined in a relevant national case, by means of an original regionally disaggregated panel dataset for Italy, a country which witnesses heterogeneous environmental performances across regions and a decentralized policy system. Our empirical analysis produces two main insights of strong policy interest. First, commitment to a more stringent waste policy tends to increase illegal disposal of waste. Second, a nonlinear bell shaped relationship exists between the number of inspections and the quantity of illegal disposal. The key message is that deterrence might only result after a relatively high level of controls is implemented. 相似文献

从理论和实证两个方面探讨了产业融合对中国装备制造业创新效率的影响,以及网络中心性和网络异质性对二者关系的调节作用。基于2006—2015年省际装备制造7个子行业面板数据,采用ISCNFI指数测度模型和基于产出距离函数的超越对数前沿分析方法,分别测度装备制造业产业融合程度及创新效率变化情况,进而利用面板回归模型对理论假设进行实证检验。结果显示:产业融合程度与中国装备制造业创新效率存在倒“U”型曲线关系,即随着产业融合程度提升,中国装备制造业创新效率呈现出先上升后下降的变化趋势;网络中心性强化了产业融合对装备制造业创新效率的提升作用,而网络异质性削弱了产业融合对装备制造业创新效率的提升作用。 相似文献

In power-oriented societies, academia may not be immune to the influence of power. This paper studies the power-publication link by applying an event-study strategy to a panel dataset of the publication and biographical information of deans of economics schools in Chinese universities. We find that (i) deanship increases an individual's publication by 0.7 articles per year; (ii) the increased publications stem from work coauthored with other researchers within the same university; (iii) the topics of the increased publications are more likely to deviate from the deans’ research area prior to becoming deans; and (iv) the power effect is smaller for top universities and leading journals, and for scholars with more pre-dean publications. These patterns appear consistent with the role of power in resource allocation rather than the impact of ability or reputation of the deans and thus have implications on distortions in knowledge production. 相似文献

This article uses a multi-country global general equilibrium (GE) model to numerically simulate the effects of possible China–US trade wars. We introduce an endogenous trade imbalance structure with trade cost into the model which helps to explore both tariff and non-tariff trade war effects. Our simulation results show that China will be significantly hurt by the China–US trade war, but negative impacts are affordable. The US can gain under unilateral sanction measures to China, but will lose if China takes retaliation measures. Comparing the effects under mutual trade war, China will lose more than the US. Introducing non-tariff barrier trade wars will intensify the negative effects, and comparatively negative effects to China are larger than to the US. Mexico’s involvement in trade war with the US will strengthen the negative effects and comparatively hurt the US more. Under non-cooperative and cooperative Nash bargaining equilibrium, the US can gain more than China in trade war negotiation, which means the US has stronger bargaining power than China. Additionally, trade wars between China and the US will hurt most countries and the world especially in GDP and manufacturing employment, but benefit their welfare and trade. 相似文献

本文研究了“同群公司”的研发支出对公司自身研发行为的影响。研究发现,同群公司研发支出越多,公司自身研发支出也越多。进一步研究发现,在公司与同群公司地理距离较近或同群公司分析师覆盖程度较高情况下,同群公司研发支出与公司自身研发支出的正相关关系更强。此外,同群公司研发支出会提高公司自身研发支出与未来业绩的正相关程度。研究表明,公司会学习同群公司的研发决策,进而改变其自身研发决策,呈现显著的研发支出同群效应;且公司信息解读成本较低时,研发支出同群效应更为显著。本文不仅丰富了关于研发支出影响因素的研究,还拓展了对研发溢出效应的研究。本文的研究结论对公司制定研发决策具有重要指导意义。 相似文献

This study appraises the value created by a bond offering in China, where high levels of state ownership and insider ownership raise concerns about the use of the proceeds. To estimate the impact of a bond issue on the firm's value, we apply an event‐study methodology on a sample of 481 issues of 347 Chinese companies over the period 2009–2013. It turns out that state ownership has a positive impact on the value of a bond offering for shareholders, which is consistent with an implicit guarantee of the issue by the state. For privately owned companies, insider ownership exerts a nonlinear impact on the firm's value, supporting an aligning effect in the use of the proceeds. Overall, the study confirms the key role of ownership structure in Chinese firms. 相似文献

This article examines the role of small- and medium-sized multinational enterprises (MNEs) in the dynamic development of global production networks (GPNs) in the maritime industry. It studies the dynamism between subsidiaries of Norwegian maritime firms and regional actors and institutions in the Greater Shanghai Region of China from the perspectives of the subsidiaries. It argues that strategic coupling, recoupling and decoupling are partly the results of regional selection mechanisms. However, in the cases where the subsidiaries are embedded within the host region, the strategies and behaviour of MNEs are of decisive importance for the dynamic development of GPNs. 相似文献

This article tests the hypotheses of convergence to a single level of total factor productivity (TFP), and a steady state of TFP growth rate in China’s agricultural sector. Based on multilateral TFP estimates we found that China’s agricultural sector has rebounded in recent years from a slower TFP growth in the 2005–2007 period. While convergence test results confirm a “catch-up” effect that provinces with lower TFP levels tend to grow faster than others, estimated rates of β convergence are conditional on how we capture the heterogeneity effect across regions. The rates of β convergence range from 0.016 to 0.039 under different model specifications. Estimates show that higher growth rates of educational attainment, R&D, and intermediate goods density (per unit of labor) can enhance TFP growth. Unfortunately, there is no evidence of an overall σ convergence, indicating that TFP levels are not converging except in the South region. It implies that to catch up with leading provinces, it would require extra efforts for those lagging behind by increasing their region-specific research investment, promoting rural educational attainment, and enhancing embodied technical change. 相似文献
