从上海国际化工城看绿色集群的创新模式 总被引:2,自引:0,他引:2
我国在发展化工产业时应当站在“绿色化工”的基础上集群式发展.避免走先污染、再治理的老路。本文以上海市国际化工城集群式发展绿色化工产业为例,在重点分析国外化工产业集群发展和金山绿色化工产业集群特点的基础上.进一步提炼了“绿色集群”的内涵及其创新意义。 相似文献

随着组团社的激增,出境游市场的竞争日趋激烈,国家旅游局提出了出境游组团社之间互为代理的市场运作设想。本文对出境游组团社互为代理的内涵、必要性和可行性进行了探讨,并借助中性联合品牌和电子商务网络,从互为代理的市场运作流程、质量保障体系和财务结算等方面初步构建了出境游组团社互为代理的市场运作模式,以期为在全国范围内推行互为代理提供一个初步的市场运作框架。 相似文献

Taxes may seem to be the most attractive instrument for curbing the emissions of carbon dioxide. This paper, however, argues that environmental taxes involve a number of serious complications — especially in an open economy riddled with market imperfections like the Netherlands. Therefore, a wide-ranging policy mix is called for. As far as households and sheltered sectors are concerned, regulation can continue to play a major role. Within the context of unilateral policies aimed at exposed sectors, the combination of subsidies and voluntary agreements may be more cost effective than the tax instrument.This paper was prepared for a conference on Energy Taxation in Europe organized by the Stichting voor Economisch Onderzoek (SEO) and held on December 13, 1991 in Amsterdam, the Netherlands. The author would like to thank Sijbren Cnossen, Jarig van Sinderen and one anonymous referee for helpful comments on an earlier draft. 相似文献

Changes in capital taxes by one economy spill onto other economies with internationally mobile capital. We evaluate these impacts using a two-region, intertemporal general equilibrium model. The foreign economy's unilateral reduction in corporate income taxation has positive but small effects on U.S. welfare. In contrast, unilateral reductions in personal income taxation impose large negative spillovers. The differences result from CIT being source-based and PIT residence-based. The CIT cut reduces tax burdens to U.S. residents who invest abroad, while the PIT cut reduces foreigners' tax burdens only. Through general equilibrium adjustments neglected in simpler models, the PIT cut lowers U.S. residents' welfare. 相似文献

The exchange of taxpayer-specific information between national tax authorities has recently emerged as a key and controversial
topic in international tax policy discussions, most notably with the OECD's harmful tax practices project and the EU's savings
tax initiative. This paper analyzes the effects of information exchange and withholding taxes, recognizing that countries
which agree to exchange information do not forfeit the ability to levy withholding taxes, and also focusing in particular
on the effects of innovative revenue-sharing arrangements. Amongst the findings are that: (i) the transfer of withholding
tax receipts to the residence country, as planned in the European Union, has no effect on equilibrium tax rates, but acts
purely as a lump-sum transfer; (ii) in contrast, allocating some of the revenue from information exchange to the source country—counter
to usual practice (though no less so than the EU agreement)—would have adverse strategic effects on total revenue; (iii) nevertheless,
any withholding tax regime is Pareto dominated by information exchange combined with appropriate revenue sharing; and, in
particular, (iv) sharing of the additional revenues raised from information provided, while efficiency-reducing, could be
in the interests of large countries as a means of persuading small countries to provide that information voluntarily.

对中国石化齐鲁分公司高硫减压渣油两种生产方案,即减压深拔工艺生产重交沥青和VRDS-FCC组合工艺生产轻质油品进行技术经济比较.结果表明:在公司裂解原料不能完全自给的前提下,VRDS-FCC组合工艺的单位利润优于减压深拔工艺,但随着重交沥青价格的上升,VRDS-FCC组合工艺的优势将逐渐减弱. 相似文献

In this article, we analyze export sophistication based on a large panel dataset (2001–2015; 101 countries) and using various estimation algorithms. Using Monte Carlo simulations, we evaluate the bias properties of estimators and show that GMM-type estimators outperform instrumental-variable and fixed-effects estimators. Based on our analysis we document that GDP per capita and the size of the economy exhibit significant and positive effects on export sophistication; weak institutional quality exhibits negative effect. We also show that export sophistication is path-dependent and stable even during a major economic crisis, which is especially important for emerging and developing economies. 相似文献

This paper examines the out-of-sample forecasting properties of six different economic uncertainty variables for the growth of the real M2 and real M4 Divisia money series for the U.S. using monthly data. The core contention is that information on economic uncertainty improves the forecasting accuracy. We estimate vector autoregressive models using the iterated rolling-window forecasting scheme, in combination with modern regularisation techniques from the field of machine learning. Applying the Hansen-Lunde-Nason model confidence set approach under two different loss functions reveals strong evidence that uncertainty variables that are related to financial markets, the state of the macroeconomy or economic policy provide additional informational content when forecasting monetary dynamics. The use of regularisation techniques improves the forecast accuracy substantially. 相似文献
