At present,the cruise industry has become the most rapidly developing industry in the modem tourism industry. The development of Chinese cruise tourism is in the ascendant, and the Chinese cruise lines are also developing and perfecting.Cruise line is an important guarantee for the sustained and healthy development of cruise tourism industry. Based on the theme of China's coastal cruise routes, this paper analyzes the layout of the global and Chinese Cruise routes, probes into the development of the cruise and cruise routes in China's domestic coastal regions, and on this basis it analyzes the current problems of the development of the domestic coastal cruise lines and puts forward some pertinent countermeasures and suggestions for the problems appearing. The purpose of this study is to provide some help for the development of the cruise industry in China, so as to open up the road for the development of the cruise tourism which is suitable for China's national conditions and vigorously promote the development of the cruise industry in China. 展开更多

[Objective] This study aimed to estimate the genetic parameters for milk yield, fat percentage, fat yield and age at first freshening of Chinese Holsteins first lactation cows in Heilongjiang under frigid-temperature and temperature zone. [Method] Records of yield and reproduction from 8 868 Chinese Holstein first lacta- tion cows from 21 herds were utilized to evaluate genetic parameters for Hei- Iongjiangs' Chinese Holsteins. Restricted maximum likelihood (REML) method was used with an animal model. [Result] The heritabilities were 0.16 to 0.34 for yields and fat percentage, 0.38 for reproduction (age at the first freshening), which were similar to estimates for temperate areas from similar methods, except for constituent percentage. Also, the estimates of genetic correlation were high between milk yield and fat yield (0.97), but were low between milk yield and fat percentage (-0.24), age at the first freshening (-0.29) and generally antagonistic. [Conclusion] Thus, es- timates of genetic parameters in this frigid and frigid-temperate environment did not differ appreciably from those that occur in temperate dairy areas. 展开更多

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. 展开更多

China's oil import dependence had risen to 72% in 2017, while its net imports of various oil products, including crude oil, refined oil, liquefied petroleum gas (LPG) and other products, had climbed to 418.8 million tons, an increase by10.7% over 2016. China's crude oil import reached 420 million tons, surpassed the United States for the first time, and China had become the biggest crude oil importing country in the world. Net export of the rejqned oil, mainly the diesel, continued to increase to 22.7 million tons, as driven by the oversupply situation of the domestic market. Last year, China's LPG import was 18.45 million tons, but its growth was diminishing. Oil price would continue to rise in 2018, while the domestic demand of refined oil would be maintained at a lower rate of growth. However, driving by new refining capacities to be brought online, it is estimated that the crude oil import would still be increased remarkably. LPG import would reach a new high due to the growth potential and strong demand for feedstocks in the petrochemical product market. 展开更多
