Highway Transportation Efficiency Evaluation for Beijing-Tianjin-Hebei Region Based on Advanced DEA Model

Regional traffic efficiency plays a key role in the development of a regional economy and its social development. How to accurately explain inherent associations and mechanisms is very significant for regional transport development and investment benefits. This paper analyses the road transport and economic development data for Beijing-Tianjin and Hebei, the Yangtze River Delta and Pearl River Delta city populations, identifies an investment and yield indicator system to effectively reflect road transport efficiency and economic development, and establishes a hybrid data envelopment analysis model based on investment indicator preferences. This model is used to compare and analyze the highway transportation efficiency of the whole Beijing-TianjinHebei region and all cities in this region. The conclusion is that the highway transportation efficiency of the Beijing-Tianjin-Hebei region is less than it is in the Yangtze River Delta and Pearl River Delta urban agglomeration, and the highway transportation efficiency of cities in the Beijing-Tianjin-Hebei region are also very different, so different investment strategies should be made for the highway transportation efficiency of different cities. The research results also indicate that improvement of the regional transportation service capability not only depends on expansion of the regional transportation scale, but also depends on improvement of the regional transportation operation efficiency, and maintains support for intensified and sustainable development routes

MEASURING THE REPAIR PERFORMANCE FOR STRICKEN CULTIVATED LAND AND AGRICULTURAL EFFICIENCY IN CHINA WITH A MODIFIED TWO-STAGE DEA MODEL

This study develops a modified two-stage DEA model based on the model of Chen and Zhu (2004) to evaluate China's agricultural efficiency and repaired efficiency (for stricken cultivated land) in a single DEA implementation. The government expenditures and the difference of various cultivated land types are identified as the external influence factors for agricultural efficiency in former works. Those are internalized into the empirical model.The results indicate that the repaired and agricultural efficiencies are positively correlated on a significant level, which implies an efficient utilization of governmental service expenditures that in turn drives high performance in agricultural efficiency. The external effects analysis finds that increasing the degree of education for agricultural employees improves the agricultural efficiency and that developing a mechanized irrigation system is beneficial in enhancing repaired efficiency for fallow land. Information on repaired cultivated land utilization, which was extracted from analysis on optimal ratios and includes the quantity of excess and deficit for each region, is also provided.Data envelopment analysis, agricultural efficiency, governmental performance, two-stage model
