The economy of the equestrian sector encompasses all the activities related to the equine world. All activities revolving around the use of a horse as entertainment, sport or business play a role in the "horse industry". These activities take place due to the existence of people demanding horses and a variety of goods and services associated with them Previous studies reveal that as income per capita becomes larger, the equestrian demand increases and, consequently, the global expenditure incurred by those individuals interested in horses. More than 500,000 horse, 9,000 breeders and 50,000 equestrian businesses, show the economic importance of the equestrian sector in Spain. That part of global expenditure that adds to the GDP of a country is what is generally defined as economic impact of the sector. Its relation will depend mostly on: the percentage of the expenditure that adds to national production and the participation in the country's global expenditure of those domestic goods and services associated with the equestrian demand. The activities related to sports are those with most economic impact, about 8,000 ∈ per horse, measured as total expenditure or with respect to the employment that they generate in the economy. 展开更多

According to the idea of cost control based on the value chain, several important factors are necessary. Firstly, it is necessary to have enough resources, which must be invested to create advantageous value chain based on customer value. It is also necessary to be sure of the cost advantage of the value chain. Secondly, the consumption of resources must be reduced as much as possible to enable the smallest operating cost for the value chain and make sure of the cost advantage based on maximum business value or profit. It is a kind of cost control from the whole view of creation and supply of value. In practice, it is also a kind of cost control system based on the value chain. It includes enough control and necessary resource investment from the view of the value creation, and keeps consumption of resources to a reasonable level from the view of the value supply. The main object of the first factor is to construct the advantageous value chain from creating customer value; and the second factor is to strengthen the advantageous value chain from supplying or producing customer value. Therefore it is a new kind of idea to explore this cost control from the whole view of creation and supply of value. It is more profitable for businesses to gain sustainable competitive advantage. 展开更多

The history of international industrialization shows that Latin American countries and former Soviet Union and Eastern European countries experienced a siginificant drop in economic growth and fell into the middle-income trap when their per capita GDP reached 4,000-7,000 international dollar (based on the 1990 prices) as a result of long-term implemented import-oriented strategy and planned economic system. Fortunately, China adopted reform and opening-up policy beginning at a lower development phase and achieved sustained high-speed growth for more than thirty years. Currently, China has surpassed the phase which the above-mentioned countries fell into the middle-income trap. On the other side, experiences of successful runner-ups show that when per capita GDP reached II,000 international dollar (based on the 1990 prices), economic growth speed will present regularly "natural drop ". Without internal and external shocks, China's economy is expected to reach this level by 2015 and the potential growth rate will possibly drop significantly. In this regard, China's toughest challenges will be whether it can effectively prevent and solve the financial risks accumulated during high-speed growth and make a shift to innovation-driven growth model Time is pressing for addressing the above challenges. A fundamental change in the growth model depends on the intensification of reform, in particular, the promotion of an "participatory and facilitative reform "approach. 展开更多

Business analysts worldwide use the standard theories and tools of macroeconomics and finance to determine the investment, trade or production possibilities in foreign markets. These evaluations are generally supported by three sources: estimations of using country-specific macroeconomic data on which they can determine patterns of growth, inflation, unemployment, productivity, income per capita, etc.; timely data on current conditions and developments in production, income and spending; and institutional information on policy makers, business practices and financial markets. This paper focuses on the first two where we examine the publically available macroeconomic data for the Kingdom of Bahrain to determine their reliability. Among our findings are: (1) creating a reliable data base of macroeconomic data is difficult due to data revision and incomplete data gathering; (2) the movement of standard macro-variables is often unusual, leading one to question further the reliability of the data; (3) based on available data it appears that the growth in Bahrain has been driven almost solely by an increase in the number of people working, with little to no apparent rise in productivity; and (4) the growth of GDP will eventually be constrained by physical limits on population growth, and can be improved only if ways can be found to increase the productivity of the workforce. 展开更多

Mining is an essential component of China's industrial economy. Using grey correlation method to analyze the correlative effect of mineral resources exploitation to relevant industries, using national income method to calculate the pulling effect of mineral resources exploitation to economic growth and using graphs as well as tables to analyze the income distribution effect, the article obtains active economic effect of mineral resources development in Bijie, Guizhou. Moreover, from the view of resources-cored effect, the article analyzes negative effects such as single industrial structure brought by mineral resource development. Through analysis, we find that mineral resources exploitation to some extent brings active effects including gross domestic product growth, local financial revenue growth and relevant industries development; however, its negative effects should not be ignored. The negative effect can be lightened by diversifying industrial structure and prolonging industrial chain. 展开更多

Regression-based decomposition of inter-industry earnings differentials shows that in 1988, 1995 and 2002, inter-industry earnings differentials made an increasing contribution to urban earnings inequality in China. The primary reason for the widening gap lay in monopoly industries. At the same time, geographical location, educational level, type of enterprise ownership, type of occupation and whether the individual had a second job also contributed to rising earnings inequality, while age and being fully employed made a decreasing contribution. Therefore, if China is to reduce the earnings gap it is imperative that we remove barriers to labor market entry and break down some monopoly industries in the product market. Additionally, reducing obstacles to the free movement of labor and improving workers' educational level should also be important elements of the government's strategy for reducing the urban income gap in future. 展开更多

Given China's dual urban-rural structure, this paper employs the Theil index for measuring and depicting China's urban-rural income disparity and its characteristics. Furthermore, this paper specifies a nonlinear threshold cointegration model to reveals a nonlinear relationship between the urban-rural income gap and real economic growth over a long period since reform and opening up in China. Our results show that the regime switch of the long-term nonlinear threshold relationship takes place at the 0.100 (threshold value) of the Theil index. From 1978 to 1991, the long-term effect of the urban- rural income disparity on China's economic growth was positive; between 1992 and 1999, there was a smooth transition to a negative effect; and from 1999 on, the negative effect has been increasing year by year. Income disparity now has the effect of retarding China's real economic growth. 展开更多

Despite widespread concerns and elevated policy debates, little is known about the Chinese public's perceptions of water pollution and willingness to cooperate with government policies. Based on survey data, this study examined Lake Tai resident perception of water pollution, willingness to pay (WTP) for water quality improvements, and its influencing factors. Contingent valuation (CV) results showed that respondents would prefer to pay 141 CNY per household a year, approximately 0.70% of their annual per capita disposable income, as an environmental fee to improve water quality in Lake Yai. Aggregate WTP for all five lakeside cities of Lake Tai was estimated at about 3.8 billion CNY, without discounts, in the next ten years. WTP was found to increase with income and female respondents were willing to pay more than males. Those respondents who were dissatisfied with water quality were more likely to pay more. The usage of Lake Tai did not strongly affect WTE 展开更多
