China's integration in the World Trade Organization (WTO) is already on its fast track. Understanding the complexity of China's dynamic adjustment resulting from its membership in the WTO and the differential regional impacts within China is very important and poses crucial challenge in evaluating its impacts. In this study, we make an attempt to incorporate seven regional commodity-detailed models into a dis-aggregated multi-sector and multi-region China Computable General Equilibrium (CGE) framework. This framework has allowed us to evaluate the impacts of China's integration into the WTO at both national and regional levels and analyze the inter-linkages between China's provincial agricultural markets. Using the framework and assumptions about factor mobility, we assess the impacts on China's agricultural and non-agricultural sectors (regionally and nationally) by reduction of its trade policy distortions, such as tariffs rate changes and quantitative restrictions. We also evaluate the structural changes on China's national and regional production and trade as China implements its commitments and moves into the WTO. 相似文献

FDI facilitated by agglomeration economies: evidence from manufacturing and services joint ventures in China 总被引:4,自引:0,他引:4
The open door policy of China’s economic reform since the 1980s has attracted heavy foreign direct investment (FDI) flows into China and especially to Guangdong (particularly the Pearl River Delta region, PRD) and induced significant economic growth during the past two decades. While there exist various classical theories of FDI in attempting to identify the determinants of FDI inflow and to explain the behavior of FDI flows, limited attention has been given from the perspective of agglomeration effects generated by a core-periphery (CP) relation.This paper intends to study the impacts of agglomerations on FDI inflows in the context of Krugman’s CP relation (1991) by investigating (1) the formation of a CP relation via gravity model analysis; (2) whether different types of industry FDI flows will respond differently in the CP-system, given agglomeration effects; and (3) whether FDI origin and firm scale matter in affecting FDI flows.A database consisting of a population frame of 37,742 firm-level manufacturing and services joint ventures investing in Guangdong in 1998 was used. Empirical results show that the agglomerations of the CP relation have affected FDI flow patterns. While both manufacturing and services FDI and sources of investment responded differently to the impacts, smaller firms were found more responsive to the CP-agglomeration settings regardless of FDI by industry type and by source. The significance and implications of the CP-system to further facilitate FDI in the region are discussed. 相似文献

This article explores the contradiction between the articulated investment policies, screening criteria or ethical charters of socially responsible investment funds and their actions demonstrated by their portfolio selection practice. The paper provides a background to socially responsible investment and Australia's contribution to greenhouse gas emissions. A discussion of renewable energy options lays the foundation for our main assertion: that this set of possible alternatives provides some new and more environmentally robust options that will better complement the underlying philosophy of funds in the socially responsible investment sector. 相似文献

This paper is interested in the modelling of the relationship between active and passive labour market policies and the aggregate unemployment outflow rate. Our model is based on a matching function and includes a simple representation of the competition between various groups of job searchers. The empirical analysis uses Belgian data. Faced with variables that are often integrated of order 1 according to the usual tests but which cannot strictly speaking be integrated, we contribute to an important methodological debate by comparing the conclusions of a classical econometric analysis and a cointegration approach. 相似文献

The EU has neither the power to tax nor the right to run a public debt. We analyze if the EU should receive the right for public indebtedness. We make use of the normative theory of public indebtedness and of positive political economy analysis. Our normative analysis identified specific cases for an appropriate use of public indebtedness. According to the political economy analysis, a misuse of public debt may be possible. As the implementation of strict constitutional constraints can limit this misuse, we propose the assignment of a right to public borrowing to the EU within tight constitutional restrictions. 相似文献

Abstract . Grossman and Helpman (1994) explain tariffs as the outcome of a lobbying process. In most empirical implementations of this framework protection is instead measured using non-tariff barriers. Since tariffs allow the government to fully capture the rents from protection, while non-tariff barriers do not, the existing parameter estimates of the protection for sale model are likely to be biased. To address this problem, we augment the framework by considering instruments that allow partial capturing. Our specification is supported by the data, where we find that only 72–75% of the rent from protection is appropriated by the government. 相似文献

Abstract: This paper examines the characteristics of firms that account for deferred tax liabilities related to government investment grants under an extended adoption timing period. Not only the recognition but also the timing decision is associated with changes in future performance and changes in the debt structure. Recognisers outperform non‐recognisers in the future, while early recognition is related to post recognition performance but only for those firms that currently perform well. Changes in the balance sheet structure are also related to both decisions. Firms with recent increases in the debt level tend to postpone recognition, while currently well‐performing firms that increase their future debt level are less likely to recognise deferred taxes. 相似文献

This article addresses the societal and cultural aspects of bioreserves and environmental restoration programmes. It begins with a discussion of bioreserves, then uses the example of a Man and Biosphere (MAB) inspired study of the US Everglades to illustrate how land has been shaped historically by culture and technology. It then demonstrates how current conflicts of values and culture, from both inside and outside the region, from interest groups with both pragmatic and emotional stances, are determining the future of an environment—the Everglades. The article thereby shows how human values and perceptions impact on the development of a sustainable Everglades, using the findings of surveys and public meetings to highlight the interests of the competing communities, ethnic and interest groups involved. If bioreserves are to survive they cannot become alienated from the people in the regions in which they are located. 相似文献

Operational Research and the environment 总被引:1,自引:1,他引:0
The discipline of Operational Research (OR) is primarily concerned with improving the effectiveness and efficiency of decision processes. These processes take place everywhere in society: industry, banking, agriculture, government, politics. Frequent use of mathematical optimization models is typical of OR. Since the early '80s these models are increasingly packaged in a user-friendly way, as Decision Support Systems. In the following we will illustrate how OR can be used to describe and solve a number of environmental problems. 相似文献
