日本出国旅游需求与人均GDP关系实证研究——兼议对我国出境旅游发展的启示

首先,基于日本1964年～2008年出国旅游相关数据,得到日本出国旅游量的收入弹性,发现日本在人均GDP(按当年价格计算)达到2000～4000美元时,出国旅游呈现爆发性增长。其次,与我国的出境旅游进行对比研究,发现我国在现价人均GDP达到3000美元时,并未出现出境旅游爆发性增长的迹象。同时,研究发现,在北京和上海人均GDP达到3000美元以上时,出境旅游呈现爆发性增长,而广州人均GDP高达8000美元以上时,出境旅游才呈现爆发性增长。

中国仍是世界最大的水泥生产需求国

水泥是建筑业最主要的原材料之一,改革开放以来,随着我国建设规模的持续膨胀和农村建房热的持续升温,国内市场对水泥的需求也与日俱增,需求的旺盛推动了水泥生产的大发展,据1979～1992年统计,我国水泥生产每年平均增长11.7％,大大超过同期其它国家同期增长速度。1992年,全国水泥产量达到30822万吨,占世界总量的20％以上,继续保持世界第一。 我国水泥产量最多的省是山东省,1992年产量达3162万吨,占全国的10.2％。

Forestry ecological footprint in China during 1973–2003

The ecological footprint （EF） model has received much attention as an assessment indicator for sustainable development in recent years. Firstly, the temporal changes of domestic timber production, imports and exports in China were analyzed from 1973 to 2003, the analysis results showed an apparent fluctuation in timber production during 1973-1995 but a decreasing trend during 1995-2002, an increasing trend in timber imports since 1995 especially after the implementation of the Natural Forest Protection Project （NFPP）, an decreasing trend year by year in timber exports since 1995. Secondly, this paper presented a time series analysis of actual forest area demand in the sustainable yield and production approach in China from 1973 to 2003, which includes both import and export forest area demand. The results showed the actual forest area demand simulated from the sustainable yield approach was slightly higher than that from the production approach during 1978-1988 and a little lower during 1989-2003; however, the actual forest area demands simulated by these two model approaches were larger than calculations that expressed in conventional forest EF. Meanwhile, the results indicated the forestry development in China during 1978-1988 was unsustainable due to overexploitation of forest stocking volumes, and China＇s forestry moved toward sustainable development since 1989 because forest resources are exploited at lower rates than they are regenerated. However, compared to forestry developed countries, the forestry development capacity in China is still lower. Finally, based on the model results we analyzed the relationships between forestry EF and the key policies, including trade policy, economic policy and forest conservation programs. In addition, several suggestions about reducing forestry EF and enhancing sustainable forestry development in China are given.

Transfer payments from the central government to the local governments and the local governments' efforts on taxation: taking China as an example

The influence of the transfer payments from the central government to the local governments on the local governments＇ efforts on taxation must be taken into consideration by every country for the design of the transfer payments. Based on the theoretical analysis on the influence of the transfer payments from the central government to the local governments＇ on the local governments＇ payments＇, this paper indicates that the local governments＇ efforts on taxation depends on the demand elasticity of the district for public goods, It increases with the increase of the elasticity. Judge the degree of the local govet：nment＇s efforts on taxation by measure 2. After an empirical analysis on the transJer payments from the central government to the local governments＇from 2000 to 2004, this paper gets the con- clusion that the local governments＇ effbrts on taxation ctbates with the increase of supporting payments or with the increase of the ratio of transfer payments to local wiliing public paymentS. Under speCific Circumstances, the higher the ratio of transfer payments to the local fiscal expenditure is. the smaller the local governments＇ efforts＇ on taxation is＂ under the central payments, whereas＇ the higher the local income is, the higher the efforts is under the central pav- ments. Based on this＇, this paper gives the meaning of its eOrresponding pofiCieS. ＂

Migration in the Middle Asia and Its Effects on the Labor Market

Many Middle Asia countries declaring their independence after the splitting of the Soviet Union, cannot meet the economical and social needs of their citizens by falling much behind of the era in terms of industry despite the natural wealth they have. In addition to all these, the problems in the ruling class and the chaos environment have resulted in the migration of many people to alternative living spaces. These migrations have affected labor market both positively and negatively besides the social life. The labor demand increased by the entrance of the immigrants into the market has affected the employee wages and also this situation has affected the life standards of the citizens In this study, the migration that took place in the countries established after the splitting of the Soviet Union, forming one of the two poles of the world before the cold war, and the effects of this migration on the labor market have been analyzed considering previous studies on the subject. The studies carried out on this subject have yielded various results according to the area in which it is carried out, the time interval it includes, and the period＇s structure For this reason, the points of views on the subject are compared by making a long literature review

Reliability and validity of the Chinese version of the Head and Neck Information Needs Questionnaire for patients with head and neck cancer and their caregivers

Objectives:This study aimed to assess the reliability and validity of the Chinese version of the Head and Neck Information Needs Questionnaire(HaNiQ).Methods:The HaNiQ was translated into a Chinese version using internationally recognized forwardand back-translation procedures.The reliability and validity of the HaNiQ were measured using Cronbach’s a coefficient,split-half reliability,exploratory factor analysis,and Pearson correlation analysis.Results:A total of 207 patients in different head and neck cancer(HNC)stages and 174 caregivers completed the Chinese version of the HaNiQ.Internal consistencies varied between good and very well(Cronbach’s α coefficient 0.74-0.90);the split-half coefficient and the content validity index(CVI)of the questionnaire were 83.5%and 83.33%,respectively.The cumulative contribution rates of the 5 subscales in patients with HNCand their caregivers were 62.41%and 61.19%,respectively.However,there are some differences between the Chinese questionnaire for caregiver and the original questionnaire regarding the attribution of items.Items 22,23,and 27 in the Psychosocial subscale of the English version were assigned to the Survivorship subscale in the Chinese version for caregivers.Conclusions:The results demonstrated that the Chinese version of the HaNiQ is a reliable and valid instrument for measuring the information needs of patients with HNC and that of their caregivers.Though the structure of the Chinese versionwas different from the English version for caregivers of HNC patients,the Chinese version of the HaNiQ appears to be reliable and would benefit from further testing.

Chinese Brands at the Crossroad？ Demand State in Kerala Markets

Globalization and liberalization offer competitive openings for several world brands to the Indian markets. Bestowed with growing disposable incomes, Kerala consumers exhibit wide diversity in their buying habits. Apparently, the emerging fascination for imported brands impels distributers to leave enough space to shelf more ＂made in China＂ brands in their showrooms. The substantial increase in consumers＇ demand for imported goods with considerable attraction for ＂made in China＂ products inspired this study to explore the demand state for various types of Chinese products in the Indian regional markets. Divided into two stages, at first, with a primary survey, the study explores the consumers＇ perception towards selected five vastly available consumer durables such as electrical appliances, handicrafts, stationeries, toys and builds wares. Later, the demand matrix developed from the primary data defines the types of demand prevailing for each category of＂made in China＂ products based on their popularity and consumption in Kerala markets.
