The present paper employs technique of geographical weighted regression (GWR) to make an empirical study of China's R&D knowledge spillovers at city level. Conventional regression analysis can only produce "average" and "global" parameter estimates rather than "local" parameter estimates which vary over space in some spatial systems. Geographically weighted regression (GWR), on the other hand, is a simple but useful new technique for the analysis of spatial non-stationarity. Results show that there is a significant difference between OLS and GWR in estimating the parameters of R&D knowledge production, and that the relationships between level of regional innovation activities and various factors show considerable spatial variability. 相似文献

Using an institutionalist reading of the capability approach, I advocate policies for enhancing financial capabilities via financial inclusion. There are 34 million unbanked and underbanked households in the USA (with 68 million adults), many of whom rely on alternative financial services providers (AFSPs). Rather than castigate AFSPs for the predatory practices of some in the industry, this paper argues that a regulated industry can be integral to meeting needs of lower-to-moderate income communities. A typology of existing financial services in the USA is the basis for presenting these proposals. The policies I evaluate concern the economy's structures and institutions rather than focusing on an individual's or a household's financial literacy. 相似文献

This study analyses the effects of exports on the level of output per capita using the panel estimates of an extended version of the Mankiw, Romer and Weil (The Quarterly Journal of Economics, CVII, 407-37, 1992) model, and on the total factor productivity using the time series estimators. The analysis is carried out for ten industries in the manufacturing sector in India. The results do not provide any evidence of convergence, and instead support the contrary evidence of divergence among industries. The exports do not induce convergence and instead seem to accentuate the process of divergence among industries. The study provides some evidence for the significant effects of exports on the level of output per capita and TFP in the manufacturing sector. The effects of exports on TFP are significant in half of the sample industries, while in the remaining half these are statistically insignificant. 相似文献

Modem economic history has shown that foreign direct investment (FDI) plays a very important role in a country‘s development. Chinese people learn this through their own experience, in a relatively short period of time, they changed their country from a close economic to the biggest FDI host in the world. In almost thirty years after the establishment of PRC, China closed the door to the rest of the world. The turning point came in 1978, when Deng Xiaping became new Chinese leader, since then open-policy prevails in China. As one important aspect of open-policy, attracting 相似文献

Coal price fluctuations and the impact on financial risk Evidence from China's coal listed companies
SHENG Hu FENG Yao-ping 《中国经济评论(英文版)》2010,9(8):32-36
With the rise of coal price, the proportion of loss-making enterprises shows an upward trend in China's coal industry. This paper uses Altman Z-Score model to measure financial risk of 19 listed companies in the coal industry in A-share market from 1995 to 2007. Empirical results show that Year-Based price index of coal price has a negative correlation with the financial risk but has no significance, and coal chain price has a significant negative correlation with the financial risk. Further research indicates that enterprises increase bad investment, and a lot of debts caused by short-term rise in coal prices. The results also show that the financial risk in the coal industry declines with the rise of GDP growth rate and increases with the rise of inflation rate. 相似文献

As the biggest developing country, China faces the heavy pressure of energy conservation and emission reduction (ECER). China’s industry takes first place in energy consumption and pollution emission among the industrial entities. How to get rid of China’s industrial stagnant growth under the restriction of resources and environment, and find out the optimal path between ECER and industrial development is the main task of this study. The article adopts the historical data of China’s industry from 2003 to 2012, establishes a managerial disposability intensity analysis framework based on the directional distance function, and designs four energy conservation scenarios and nine CO2 emission paths for a total of 36 kinds of alternative policy combinations to predict the win–win development and find the optimal path of industrial ECER from 2013 to 2050. Research shows that on the whole, industry will fail to achieve a win–win development in the future, while 6% growth rate of industrial output, 2.8% growth rate of energy consumption, and the peak of CO2 in 2040 is the most optimum path. At the same time, the feedbacks of ECER constraints on specific industrial sectors are different, there are 16 industrial sectors that can achieve win–win development in the future. 相似文献

The strenuous fluctuation in global asset price in recent years has had a profound impact on the economic and social development
of every country. An empirical analysis indicates that asset prices (the stock price index and real estate prices) are important
endogenous variables affecting the interest rate reaction function of central bank monetary policy. With expected inflation
as a given, each one percentage point rise in output gap will cause a 0.79 percentage point reduction in interest rates by
the central bank and each one percentage point rise in real estate price will result in a 2.2 percentage point rise in interest
rates. The stock price index does have an influence on the trends in monetary policy, but it is less salient than the impact
of housing prices. We also show that monetary policy that employs asset price as an endogenous variable increases the central
bank’s control in seeking to attain its objectives. Therefore we suggest that the central bank should make asset price fluctuation
an endogenous variable and incorporate it into its forward-looking interest rate rule, in order to facilitate the healthy
development of China’s markets for real estate, stocks and derivatives, energy and bulk commodities and maintain rapid, smooth,
sustainable and harmonious economic development. 相似文献

Total factor productivity (TFP) is a measure of long-term economic growth and a comprehensive industry-level productivity measure. There are large gaps in China’s regional construction industry development due to unbalanced regional economy. Based on TFP measurement, this article puts forward a two-hierarchical analysis framework with coefficient of variation, Moran scatterplot and coefficient of convergence to analyse change trend of the construction industry TFP in three major regions in terms of spatial diversity, correlation and convergence. Then, the geographically weighted regression model is utilized to explore the influencing mechanism on the TFP. The results indicate the differences of the regional construction industry TFP are enlarging. There is obvious spatial correlation and heterogeneity in the regional TFP without a relatively stable space pattern. The TFP also exhibits convergence effects among three major regions. The construction industry productivity in all regions is significantly affected by economic environment, industrial organization structure and technological level. Industrial organization structure exerts the various influences on the productivity in different regions. 相似文献

In China, the tourism industry is regarded as one means of fostering local economic development. This paper tries to examine inbound tourism development in China in the last decade and analyze inbound tourism's satisfaction of their travel experience with tourist attractions, facilities, services and price by an empirical study based on the investigation of Lanzhou, Wuhan, Guangzhou, Shanghai and Beijing. This paper discusses the demographic characteristics of visitors from Hong Kong, Macao and Taiwan, US. Korea and Japan by surveying a .sample of 528 visitors in five different cities. The survey showed that four provinces/autonomous region in western China ranked the top 10 popular destinations. Chinese natural landscape, culture and food were highly regarded by the tourists. At the same time, tourists expressed less satisfaction with tourist language convenience, tourist facility and nightlife in China. It was also found that only 7.4% of the tourists thought travel in China was far more than what they had paid, that 6.5% regarded they got what they paid for, and that 34.9% thought the travel cost was reasonable. Most tourists were satisfied with their travel experience in China: many of them would like to return to China and would like to recommend China. For the sustainable development of tourism, Chinese tourism authorities should strengthen the construction, propaganda and management of scenic spots, improve tourist facility and tourist education. especially language convenience, and strengthen the supervision of tickets, souvenir and hotel price. 相似文献
