求翻译：For the urban-rural income gap between the formation of the reasons, many scholars see it as the industrialization process in the dual economic structure of the product, namely, that China's social production as the main features of an advanced urban economy and to small-scale production as the main features of the backward co-existence of the economic structure of rural economy is the income gap between urban and rural residents in China caused by the formation of the main reasons. Moreover, in recent years, scholars have through the establishment of model, the dual economic structure on the urban-rural income gap between the extent of the impact measure, the results also supported this conclusion. National Bureau of Statistics of China Rural Investigation Corps Task Force from 1978 to 1993 and the income gap between urban and rural residents in the dual structure coefficient, the value of agricultural product prices lower than the proportion of hidden income of urban residents in the proportion of income of rural residents in the proportion of non-agricultural industries and urban-rural Population ratio influencing factors such as the relationship between the Metrology and Inspection, test results show that the dual structure coefficient explains the income gap between urban and rural residents 59.62%, indicating China's urban-rural dual economic structure is divided income gap between urban and rural residents in the most fundamental reason for change. Chen Zongsheng through a simple dual economy model, from a theoretical explanation, in the dualistic economy, decided to urban-rural income gap is largely attributable to the agricultural and non agricultural dual contrast factor, the burden of urban and rural employment coefficient ratio, the two sectoral allocation coefficient and rural level of industrialization. And take advantage of China from 1978 to 2002 carried out the relevant data, quantitative analysis, results show that these four factors can explain the income gap between urban and rural areas in China during the period of 89%.是什么意思？
