生产性服务业与先进制造业的互动与融合——基于甘肃省投入产出表的实证分析 总被引:5,自引:0,他引:5
文章在中国生产性服务业与制造业互动与融合发展的背景下,利用甘肃省2002年和2007年投入产出表的相关数据,采用相关指标,详细分析了甘肃省生产性服务业发展现状以及与先进制造业互动与融合的情况。结果表明,甘肃省先进制造业对其他部门的拉动作用要大于生产性服务业对先进制造业的促进作用,生产性服务业仍需进一步加强发展。 相似文献

This paper investigates the business cycle co‐movement across countries and regions since 1950 as a measure for quantifying the economic interdependence in the ongoing globalisation process. Our methodological approach is based on analysis of a correlation matrix and the networks it contains. Such an approach summarises the interaction and interdependence of all elements, and it represents a more accurate measure of the global interdependence involved in an economic system. Our results show (1) the dynamics of interdependence has been driven more by synchronisation in regional growth patterns than by the synchronisation of the world economy, and (2) world crisis periods dramatically increase the global co‐movement in the world economy. 相似文献

This paper addresses the stability of a multimarket competitive equilibrium. The dependence of stability on the choice of the numeraire is clarified. The traditional tâtonnement pricing is revised in order to satisfy some basic features of economic behaviour. Well‐known conditions for local stability are proved to be insufficient if a market for credit is introduced alongside the markets of dated commodities. Stability depends not only on the slopes of the demand and supply curves, but also on equilibrium prices. This result emerges without the occurrence of capital perversities, such as reswitching and reverse capital deepening. 相似文献

Modeling exchange rate passthrough after large devaluations 总被引:1,自引:0,他引:1
Large devaluations are generally associated with large declines in real exchange rates. We develop a model which embodies two complementary forces that account for the large declines in the real exchange rate that occur in the aftermath of large devaluations. The first force is sticky nontradable-goods prices. The second force is the impact of real shocks that often accompany large devaluations. We argue that sticky nontradable goods prices generally play an important role in explaining post-devaluation movements in real exchange rates. However, real shocks can sometimes be primary drivers of real exchange-rate movements. 相似文献

The best predictor of current investment at the firm level is lagged investment. This lagged-investment effect is empirically more important than the cash-flow and Q effects combined. We show that the specification of investment adjustment costs proposed by Christiano et al. (2005) predicts the presence of a lagged-investment effect and that a generalized version of their model is consistent with the behavior of firm-level data from Compustat. 相似文献

Mobile games are a prime example of a successful mobile application and demonstrate the increasing range of platforms for the media and entertainment industries. Against this convergent background, this paper introduces the basic features of the mobile gaming market and its industrial ecosystem together with its main actors and activities. The focus of the paper lies in the challenges ahead for the evolution of mobile applications into a potentially dominant game platform and the possible disruptions along this road. The deep personal relationships between users and their mobile devices are considered to further explore the link between mobile games, players’ strategies and pending techno-economic developments. The paper concludes with a brief discussion of some policy options to assist with the development of this domain. 相似文献

The prerequisite for a sustainable and equitable use of common resources (the so-called Commons) must be the proper evaluation of their role within the complex network of relationships that ensure ecosystems functioning, resilience, and evolutionary dynamics. It is crucial to ascertain to what extent the common wealth is used for the common benefit. Money-based schemes for valuing the Commons, such as the so-called “willingness-to-pay”, provide a user-side evaluation perspective based on the idea that value only stems from utilization by humans. As a complement to such a point of view, we present and discuss in this paper a donor-side evaluation method (Emergy Synthesis) based on the idea that a proper measure of value can be achieved by also accounting for the work done by the biosphere in generating services and resources. It should not be disregarded that such resources and services also provide support to other species in the web of life. Emergy, a scientific measure of such environmental support, is suggested as a tool capable to assess quantity and quality of shared resources, thus providing a basis for their environmentally sound management. 相似文献

Port workers services have been usually heavily regulated and reserved exclusively for a special kind of workers, dockworkers,
which seems to have been the cause of serious inefficiencies worldwide. During the eighties, law reforms have been introduced
to solve this problem. In this paper we analyze and decompose efficiency in cargo handling operations in 19 Spanish ports
from 1990 to 1998. The method chosen is that of the parametric estimation of both allocative and technical inefficiency using
panel data and a quadratic cost function. Results show that although inefficiency has decreased overall, there has been over
utilization of labor regarding capital, and technical inefficiency. This supports the need of further consideration of other
aspects including competition.

The geographical allocation of Spanish aid has been little studied, despite its unusual concentration on middle-income countries. This paper develops a theoretical model in which aid allocation depends on a combination of recipient needs, donor interests and performance criteria, and estimates it econometrically for Spain. The results show that the allocation of Spanish aid has been influenced both by Spain's own foreign policy interests and by recipient needs for poverty reduction and development (although not by the quality of recipient governance or recipient absorptive capacity). Former Spanish colonies received a disproportionate share of Spain's aid (as is true mutatis mutandis for other European countries), but aid is allocated among them with greater regard to recipient need than is Spain's aid to other developing countries. 相似文献
