皖江城市带中间阶层体育消费需求结构的数量分析

Quantitative analysis of the structure of sports consumption needs of people in the middle stratum in cities in the Wanjiang region

利用2007～2008年皖江城市带城镇居民住户的体育消费调查数据,运用ELES模型对中间阶层居民体育消费需求结构进行实证分析。结果显示:居民经济收入是影响体育消费结构的最重要因素,社会资源、文化资源以及闲暇时间也是制约体育消费结构的重要因素;目前中间阶层居民体育消费主要以体育实物性消费为主,但这种主体地位正受到体育劳务型和体育文化信息型消费的挑战;体育消费的边际消费倾向为0.031 1,其中对实物类、参与类的边际消费倾向大于观赏类、文化信息类的边际消费倾向;各项体育消费商品的需求收入弹性系数均为正值,各类体育商品的支出受自身价格变化的影响较大,而受其它消费品价格变化的影响较小。

By utilizing the data of survey on sports consumption of residents in cities in the Wanjiang region between 2007 and 2008, the authors applied the ELES model to perform an empirical analysis on the structure of sports consumption needs of residents in the middle stratum, and revealed the following findings： residents＇ economic income is the most important factor that affects the structure of sports consumption, social resource, cultural resource and leisure time are also important factors that confines the structure of sports consumption; currently the sports consumption of residents in the middle stratum is mainly real sports consumption, but this principal status is being challenged by sports labor type and sports cultural information type consumption; the marginal propensity to consume of sports consumption is 0.031, in which the marginal propensity to consume of real and participation type items is greater than the marginal propensity to consume of appreciation and cultural information type items; the coefficients of income elasticity of needs for various sports consumables are all positive values; the expenditure on various sports commodities is significantly affected by their own prices, but not so significantly affected by the prices of other consumables.
