Abstract
“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.

Through solving the data envelopment analysis (DEA)-slackbased measure (SBM) model and comparing the results of each model, this study provides the details of measuring urban-rural spatial performance changes in 2018, 2000, and 2010 by an increasing spatial efficiency of the urban-rural space degree

Summary
The paths for developing the urban-rural space focus on the long-term growth and macrolevel organization of towns and rural areas as discussed by Addae and Oppelt [1, 2]. As built-up lands and urban areas have grown to enormous sizes, the construction boundaries between counties are regularly breached, and severe hollowing occurs in rural areas. Apart from the low urban-rural spatial performance, in many developing and emerging countries around the world, there is a growing contradiction between the shortage of indicators for construction land in urban areas and the abundance of unoccupied construction land and wastelands. Long-term urban-rural characteristics emerge, including unique neither-rural-nor-urban landscapes, overlapping spaces in towns (rural areas), counties, and cities, and severe “plagued and mosaic” land parcels as discussed by Munthali et al [4]. The overall urban-rural spatial performance remains low
