The study of the Yangtze River Delta urban agglomeration provides a reference for regional construction. We set up a suitable cluster model and a comprehensive evaluation model to evaluate the urban economic development and provide the basis for the government to formulate and adjust the economic measures. We use the heat map of correlation coefficient to eliminate the economic indicators that are less correlated with per capita GDP and use grey correlation analysis to detect the degree of correlation of economic indicators. The optimal method is determined by comparing the results of K-means clustering and fuzzy C-means clustering. In addition, we use principal component analysis to rank the status of urban economic development. The results show that the relationship between the added value of primary industry, the added value of agriculture, forestry, animal husbandry and fishery, and per capita GDP is close to 0. Regional development level is not balanced. Chizhou, Xuancheng, Bengbu, and other cities lag behind in the economic rankings. Finally, it is suggested to reform the laggard cities and try to improve their economic strength from various economic indicators.

The Impact

Purpose – The impact of dietary changes associated with urbanization is likely to increase the demand for land for food production. The purpose of this paper is to examine the impact of urban economic development on changes in food demand and associated land requirements for food production. Design/methodology/approach – Based on economic estimates from the Almost Ideal Demand System, feed conversion ratios, and crop yields, the authors forecast and compare future dietary patterns and land requirements for two types of urban diets in China. Findings – The results show that the expenditure elasticities of oil and fat, meat, eggs, aquatic products, dairy, and liquor for the diet of capital cities are greater than those for the diet of small- and medium-sized cities. The authors forecast that capital city residents will experience a more rapid rate of increase in per capita demand of meat, eggs, and aquatic products, which will lead to much higher per capita land requirements. Projections indicate that total per capita land demand for food production in capital cities will increase by 9.3 percent, from 1,402 to 1,533 m2 between 2010 and 2030, while total per capita land demand in small- and medium-sized cities will increase only by 5.3 percent, from 1,192 to 1,255 m2. Originality/value – The results imply that urban economic development can significantly affect the final outcomes of land requirements for food production. Urban economic development is expected to accelerate the rate of change toward an affluent diet, which can lead to much higher future land requirements.

The City

Contemporary trends on the world tourism market show that the number of tourists attracted by the cities in growing. Urban tourism is a growing tourism market and especially are attractive the cities in Europe. The cities as an important tourist destinations came of age during 1980s. The local governments came to recognize that tourism could have a role in urban economic development. The invisibility of tourism in cities partly arises from the fact that many facilities are used both by residents and visitors. Improving these facilities therefore provides benefits for local residents as well as assisting the promotion of tourism. City tourism development plan should be prepared as an integral part of global economic and social development plan of the city, with the main aim to integrate the tourism in existing urban economic development, and at the same time to prevent conflict situations. Tourism development in the city needs a network and cooperative relationships between local government, tourist organization, tourist agencies and different organizations/institutions in the city; public-private partnership is a must. In the paper are analyzed the main attributes, principles and goals of the tourism in the cities.
