“…The results showed that the higher the city's administrative level, the greater the inefficiency of urban production. Jin et al [25] used SFA to evaluate land-use efficiency, ecological efficiency, and ecological performance of each county in mainland China's Hubei Province in the face of rapid urbanization. Their findings provide a valuable reference for the development of new urban areas, the efficient utilization of available land, and the protection of ecological values.…”

A strong construction industry is critical to any country’s economic and infrastructural development. Facing declining business prospects in the domestic market, Taiwanese construction firms have sought new opportunities overseas, particularly in the mainland Chinese market. Without an adequate understanding of the market, making such investments involves significant risks. To better understand the differences in the markets, this study investigates the technical efficiency (TE) of the Taiwanese construction industry compared to mainland China. The focus was on TE values of construction companies across the two markets as well as the strengths and weaknesses to help inform the decision-making process. The TE evaluation was completed using the stochastic frontier approach (SFA) with a subinput efficiency model to evaluate three inputs (assets, costs, and labor) of 123 construction companies with 59 companies in mainland China and 64 companies in Taiwan. Results show that for the key asset investment factors in Taiwan’s construction industry, TE is lower than that in mainland China. However, Taiwan’s construction industry was found to have higher labor efficiency than mainland China. Relative to mainland Chinese companies, Taiwanese companies have advantages in both labor inputs and revenue outputs but are disadvantaged in terms of the firm and market size. This study shows that Taiwanese construction firms are positioned to pursue expansion into mainland China, ideally by establishing cooperative alliances. Results also show that government policy needs to ensure construction companies are supported by increased economic freedom and reduced restrictions, as these positively correlate with the revenue of local construction companies.

“…As the ecological governance technology advances, a large number of studies have proposed to relieve the contradiction between urban sprawl and habitat destruction by means of the construction of urban ecological network 3 . The construction of ecological network can not only promote the circulation of ecological materials and energy in the city, but also is of great significance for urban ecological spatial planning and the realization of regional sustainable development 4 .…”

With the rapid advancement of urbanization and industrialization, ecological patches within cities and towns are fragmented and ecological corridors are cut off, regional ecological security is threatened and sustainable development is hindered. Building an ecological network that conforms to regional realities can connect fragmented patches, protect biodiversity and regional characteristics, and provide scientific reference for regional ecological protection and ecological network planning. By taking Qilin District, the main urban area of Qujing City as an example, and using geospatial data as the main data source, based on morphological spatial pattern analysis (MSPA) and minimum cumulative resistance (MCR), this study identified ecological source areas, extracted ecological corridors, and build & optimize ecological networks. (1) All landscape types are identified based on MSPA, the proportion of core area was the highest among all landscape types, which was 80.69%, combined with the connectivity evaluation, 14 important ecological source areas were selected. (2) 91 potential ecological corridors were extracted through MCR and gravity models, there were 16 important ones. (3) The network connectivity analysis method is used to calculate the α, β, and γ indexes of the ecological network before optimization, which were 2.36, 6.5, and 2.53, while after optimization, α, β and γ indices were 3.8, 9.5 and 3.5, respectively. The combined application of MSPA-MCR model and ecological network connectivity analysis evaluation is conducive to improving the structure and functionality of ecological network.
