The nature and framework of the valley economy model are described and the development of the model, which is specific to the mountain areas of Beijing, is analyzed. Five different valley economy models applied in the Beijing mountain areas are compared. The major purpose of the valley economy model is to develop the regional economy, including the selection of appropriate industries, the allocation of industrial space, the establishment of supply chains and the integration of various industries. Pilot experiments using the valley economy model have been conducted in seven counties(districts) in Beijing: Pinggu, Huairou, Changping, Mentougou, and Fangshan districts, and Yanqing and Miyun counties. Five models for developing the Beijing mountain areas have been explored, including: creative cultural industries, characteristic industry clusters, the promotion of large tourist areas, natural scenic tourism and folk cultural tourism. Each model has its own unique features and potential to help in the regional development of mountain areas.展开更多

Recently some methods of exploratory spatial data analysis such as spatial autocorrelation have provided effective tools to analyze spatial agglomeration and cluster, which can reveal the pattern of regional inequality. This article attempts to use spatial autocorrelation at county level to get refined spatial pattern of regional disparity in Chinese northeast economic region over 2000-2006 (2001 absent). The result indicates that the basic trend of regional economy is an increasing concentration of growth among counties in northeast economic region, and there are two geographical clusters of poorer counties including the counties in western Liaoning Province and adjacent counties in Inner Mongolia, poorer counties of Heihe, Qiqihar and Suihua in Heilongjiang Province. This article also reveals that we can use the methods of exploratory spatial data analysis as the supplementary analysis methods in regional economic analysis.展开更多

However, a methodology to identify and analyze policy-relevant economic cluster dynamics is still not well developed. Based on input-output(I-O) data of 1987, 1992, 1997, 2002 and 2007 of Beijing, this article presents an adapted principle component analysis for identifying the evolution of local economic cluster patterns. This research addresses the changes of economic interaction of industries with complementary and common activities over time. The identified clusters provide an insight into the reality of economic development in a diversifying urban economy: the increasing importance of services and the growing interaction between service and manufacturing industries. Our method therefore provides the analysts with a better understanding of the emergence, disappearance and development of economic clusters citywide. The results could be used to assist monitoring urban economic development and designing more practical urban economic strategies.展开更多

This is because resource-based cities' economic development has fallen below general levels due to resource exhaustion and an unbalanced industrial structure, among other factors. Further, an economic gap has long existed between Northeast China's large number of resource-based cities and non-resource-based cities. This article comprehensively studies the economic convergence of Northeast China's resource-based cities and non-resource-based cities from 1996 to 2015 by using a dynamic panel to analyze not only the economic development of different industries and types of cities, but also the main factors that influence economic development. The empirical results demonstrate that economic convergence exists in both resource-based and non-resource-based cities, but the economic gap between them has clearly narrowed since the implementation of a strategy to revitalize the Northeast's old industrial base. Shrinking cities are the fastest to converge, as mature cities are slower and regenerating cities are the slowest; regarding industry structure, the secondary industry dominates the economy in mature and shrinking cities, and the tertiary industry in regenerating cities. The primary stimulus in resource-based cities' economic development involves upgrading the industrial structure and investing in human capital. As China faces a ‘new normal' economy, resource-based cities in Northeast China should restructure the economy and perfect their market system to avoid again widening the economic gap.展开更多

In this paper, the impact of urban agglomeration on labor productivity is explored by making comparisons among these four cities. The model used for analysis is a classical model derived from previous studies. Some indicators, such as population density and economic density, were selected to examine the impact of urban agglomeration on the labor productivity based on the time-series data for the four cities from 1990 to 2007. The four main conclusions are: l) The promotion from the growth rate of population density on the growth rate of labor productivity is limited. 2) The negative relationship exists between the growth rate of employment density and the growth rate of labor productivity. 3) Agglomeration effect exists in the four cities, the highest one is Dalian, Shenyang takes the second place, followed by Changchun and Harbin, and the predominant promotion exerted on the labor productivity is the output density.展开更多

The largest monitored subsidence gradient of 7.9×10-3 and magnitude of 91 cm were firstly derived by theoretical derivation. Then, the stronger phase maintaining capacity and weaker sensitivity to minor land subsidence compared with C-band DInSAR were illustrated by phase simulation of the actual mine subsidence. Finally, the data processing procedure of two-pass DInSAR was further refined to accurately observe subsidence of a coalfield of Jining in Northern China using 7 ALOS PALSAR images. The largest monitored subsidence magnitude of 39.22 cm and other properties were better investigated by testing results interpretation and subsidence analysis, and the absolute difference varying from 0.5 mm to 17.9 mm was obtained by comparison with leveling-measured subsidence. All of results show that L-band DInSAR technique can investigate the location, amount, area and other detailed subsidence information with relatively higher accuracy.展开更多

The Chinese economic growth has influenced tremendously on the world economic development. Being Chinese close neighbor, how has the Northeast Asia be influenced? This paper will elaborate from the following three aspects: Chinese economic increase made China become important strength to promote the process of regional cooperation; Chinese economic increase made the pattern of Northeast Asian cooperation in economy and trade changed; competition and difference that Chinese economic increase brought to Northeast Asia. The increase of Chinese economic has positive influence on the economy of Northeast Asia, and is one of the powers causing the Northeast Asian economy to grow. At the same time, this kind of influence is mutual. In particular the economic cooperation with Japan is the key to establish the integration of the Northeast Asian economy.展开更多

In spite of various common causes for the Arab uprisings, the paper spotlights the "Youth role" and its regarded issues of "Youth Bulge", "Education" and "Unemployment" with a glimpse to the overturned regimes of "Tunisia, Egypt, Libya, and Yemen". According to published statistics these countries are among the countries with the highest rate of youth as working age population in MENA. Therefore, the paper is to present the importance and impact of youth as a social parameter in challenging political structure of the countries in the MENA and leading to topple their political systems. Thus, the paper reasons the MENA political upheavals, in general, and the mentioned countries' uprisings, in particular, can not be well understood disregarding to natural tensions between economic, population structures, and political demographic challenges. This is to be done drawing on data from different international institutions. The intervened variables such as "ethnicity, race, religion and sexuality" and international parameters have not been considered.展开更多

According to the characteristics of Harbin City in Northeast China, an indicator system including five subsystems and 37 indicators was established for comprehensive evaluation on urban sustainable development. The development indexes of all urban subsystems and complex system were calculated quantitatively using the comprehensively integrated methods composed of Principle Component Analysis, Analytic Hierarchy Process and weighed index method, and then the comprehensive level of ur- ban sustainable development and the degree of urban interior coordination were analyzed. The results indicated that 1) the overall urban development presented an uptrend, however, the interior development was not well balanced from 1996 to 2006; 2) the development in each subsystem presented a strong fluctuation; and 3) the development in re- sources subsystem showed a downtrend. Based on those results, the suggestions of urban sustainable development were put forward at the end.展开更多

In this paper, the issue of the Eurozone cohesion is analyzed, with emphasis on the North-South axis. The dynamics of 10 economic variables covered the general performance (GDP, consumption), price environment (prices and interest rates), both public and private financial variables and competitiveness (real effective exchange rates, unit labor costs etc.). The complex analysis of the data indicates that whereas in the most of analyzed variables neither convergence nor divergence can be identified, in the all important competitiveness area the long term divergence between the North and the South of the Eurozone is undeniable. Unless addressed, this dynamics may constitute significant, and perhaps ultimate, threats to the Eurozone cohesion and perhaps to its existence.展开更多

The authors tried to find the answers to the questions such as "How bad or good is the situation there?" and "what is the expectation about the future of the region?" Like other countries around the world, the MENA oil exporters, comprised of Algeria, Bahrain, Iran, Iraq, Kuwait, Libya, Oman, Qatar, Saudi Arabia, Sudan, United Arab Emirates, Yemen were adversely affected by the global crisis. The MENA oil exporters are recently recovering from their recession in 2009 when the global crisis was felt intensively there. GDP in the region has grown by 3.5 percent in 2010 after a low growth of 0.7 percent in 2009. The average real GDP growth excluding Libya is projected to reach 4.9 percent in 2011. Two developments mark the outlook: the unrest in the region and the surge in global fuel and food prices. For most oil exporters, the expected increase in oil prices and production volumes will lead to higher growth in 2011 and stronger fiscal and external balances, notwithstanding recent increases in government spending. The oil exporters' combined external current account surplus is estimated to increase. The effects of the political events in Tunisia and Egypt have spread in varying degrees to the MENA oil exporters in the region, and many of these countries are responding with public spending and job-creation measures to alleviate social tensions. The social unrest also highlights the need to pursue fundamental economic reforms--social policy, fiscal management, governance, business environment, labor markets, and financial sector access to facilitate more inclusive economic growth. While the MENA countries are generally divided into two sub-regions such as "oil exporters" and "oil importers" in the economic literature, the authors will deal with only the MENA oil exporters in this work. The negative effects of the global crisis in these countries on growth, inflation, current account balance, budget balance, and finally financial sector will be reviewed in this work and the expectations and the developments which occurred after the crisis in these countries will be dealt with especially in the context of the IMF reports.展开更多

文摘It is an effective way in realizing urban coordinated and sustainable development to establish a series of in- dicators and to evaluate urban environmental and socioeconomic development. According to the characteristics of Harbin City in Northeast China, an indicator system including five subsystems and 37 indicators was established for comprehensive evaluation on urban sustainable development. The development indexes of all urban subsystems and complex system were calculated quantitatively using the comprehensively integrated methods composed of Principle Component Analysis, Analytic Hierarchy Process and weighed index method, and then the comprehensive level of ur- ban sustainable development and the degree of urban interior coordination were analyzed. The results indicated that 1) the overall urban development presented an uptrend, however, the interior development was not well balanced from 1996 to 2006; 2) the development in each subsystem presented a strong fluctuation; and 3) the development in re- sources subsystem showed a downtrend. Based on those results, the suggestions of urban sustainable development were put forward at the end.
文摘Do Eurozone's countries converge or diverge over time? In this paper, the issue of the Eurozone cohesion is analyzed, with emphasis on the North-South axis. The dynamics of 10 economic variables covered the general performance (GDP, consumption), price environment (prices and interest rates), both public and private financial variables and competitiveness (real effective exchange rates, unit labor costs etc.). The complex analysis of the data indicates that whereas in the most of analyzed variables neither convergence nor divergence can be identified, in the all important competitiveness area the long term divergence between the North and the South of the Eurozone is undeniable. Unless addressed, this dynamics may constitute significant, and perhaps ultimate, threats to the Eurozone cohesion and perhaps to its existence.
文摘Our research topic is about the economic situation in the Middle East and North Africa (MENA) oil exporters after the global crisis in 2008. The authors tried to find the answers to the questions such as "How bad or good is the situation there?" and "what is the expectation about the future of the region?" Like other countries around the world, the MENA oil exporters, comprised of Algeria, Bahrain, Iran, Iraq, Kuwait, Libya, Oman, Qatar, Saudi Arabia, Sudan, United Arab Emirates, Yemen were adversely affected by the global crisis. The MENA oil exporters are recently recovering from their recession in 2009 when the global crisis was felt intensively there. GDP in the region has grown by 3.5 percent in 2010 after a low growth of 0.7 percent in 2009. The average real GDP growth excluding Libya is projected to reach 4.9 percent in 2011. Two developments mark the outlook: the unrest in the region and the surge in global fuel and food prices. For most oil exporters, the expected increase in oil prices and production volumes will lead to higher growth in 2011 and stronger fiscal and external balances, notwithstanding recent increases in government spending. The oil exporters' combined external current account surplus is estimated to increase. The effects of the political events in Tunisia and Egypt have spread in varying degrees to the MENA oil exporters in the region, and many of these countries are responding with public spending and job-creation measures to alleviate social tensions. The social unrest also highlights the need to pursue fundamental economic reforms--social policy, fiscal management, governance, business environment, labor markets, and financial sector access to facilitate more inclusive economic growth. While the MENA countries are generally divided into two sub-regions such as "oil exporters" and "oil importers" in the economic literature, the authors will deal with only the MENA oil exporters in this work. The negative effects of the global crisis in these countries on growth, inflation, current account balance, budget balance, and finally financial sector will be reviewed in this work and the expectations and the developments which occurred after the crisis in these countries will be dealt with especially in the context of the IMF reports.
