“Smart growth” is an urban planning concept. In this paper, the overall urban-rural smart growth efficiency is explored, which serves as an indicator to effectively measure the allocation of urban-rural spatial resources and structural rationality of the urban-rural space. Taking a developing county city in northwest China plains area as an example, the urban-rural spatial efficiency system was established and the evaluation model constructed by using the data envelopment analysis (DEA)-slack-based measure (SBM) model. The model was used to empirically analyze the characteristics in 2000, 2010, and 2018. The results show that the urban-rural spatial efficiency of the urban-rural space degree of a county in northwest China plains area exhibits growth trend on the whole, and scale efficiency increases the most. The increase of technical efficiency promotes the growth of spatial performance, which is mainly manifested in the construction of industrial parks. Although urban and rural spatial performance has made great achievements, there are still problems. Results of the test for each city indicate that the method proposed in this study is, in fact, quite effective in evaluating the smart growth pattern for developing cities. Finally, the corresponding improvement social and economic policies’ strategy is proposed.

西北平原发展中地区城市智慧增长空间绩效测度

“智能增长”是一种城市规划概念。本文探讨了城乡整体智能增长效率，为有效衡量城乡空间资源配置和城乡空间结构合理性提供了指标。以西北平原地区发展中的县城为例，建立了城乡空间效率系统，并建立了基于数据包络分析（DEA）-基于松弛的测度（SBM）模型的评价模型。利用该模型对2000年，2010年和2018年的特征进行了实证分析。结果表明，西北平原一个县城乡空间度的城乡空间效率总体上呈现增长趋势，并且规模效率增加最多。技术效率的提高促进了空间性能的增长，这主要体现在工业园区的建设中。尽管城乡空间绩效取得了巨大成就，但仍然存在问题。每个城市的测试结果表明，本研究中提出的方法实际上在评估发展中城市的智能增长模式方面非常有效。最后，提出了相应的社会经济政策改善策略。在评估发展中城市的智慧增长模式方面非常有效。最后，提出了相应的社会经济政策改善策略。在评估发展中城市的智慧增长模式方面非常有效。最后，提出了相应的社会经济政策改善策略。
