“…For another, operational efficiency is a significant indicator to measure the development quality and technical level of HTZs. Li [11] took the operational efficiency as the starting point, and explored the key factors that affect its development, so as to promote the further development of HTZs. Ma and Goo [3] studied the relative efficiency and total factor productivity (TFP) change of the zones in China with the data envelopment analysis (DEA) and Malmquist productivity index (MPI).…”

High-tech zones (HTZs), as important economic growth poles, have played a key role in China’s economic boom. A method based on multi-criteria decision-making (MCDM) and particle swarm optimization (PSO) is proposed to evaluate economic benefits of HTZs. MCDM involves analytic hierarchy process (AHP) and technique for order preference by similarity to an ideal solution (TOPSIS) as they are easy and simple to calculate. AHP is used to construct judgment matrix. Then, the judgment matrix is converted to a constraint optimization problem. PSO is adopted to optimize the problem and get weights of indicators. TOPSIS is used to make the evaluation. The results from 2012 to 2016 of 105 HTZs are obtained and hierarchical clustering analysis is applied to cluster results. The results have demonstrated that the rankings of Zhongguancun Technology Park and Wuhan East Lake HTZ have always been at the forefront, and the ranking of Kunshan New District has risen rapidly, while Shenyang HTZ has dropped significantly. According to the results, some targeted suggestions have been proposed for the development of HTZs.

“…Several different housing reconstruction options were offered to disaster survivors (e.g., self-construction, government-led reconstruction, and joint reconstruction) in the STGLR plan [64]. However, most farmers chose the concentrated rural settlements, accommodating tens of thousands of disaster survivors, due to their low reconstruction capacities.…”

This study contributes to an in-depth examination of how Wenchuan earthquake disaster survivors utilize intensive built environment reconstruction outcomes (housing and infrastructural systems) to facilitate their long-term social and economic recovery and sustainable rural development. Post-disaster recovery administered via top-down disaster management systems usually consists of two phases: a short-term, government-led reconstruction (STGLR) of the built environment and a long-term, survivor-led recovery (LTSLR) of human and social settings. However, current studies have been inadequate in examining how rural disaster survivors have adapted to their new government-provided housing or how communities conducted their long-term recovery efforts. This qualitative case study invited sixty rural disaster survivors to examine their place-making activities utilizing government-delivered, urban-style residential communities to support their long-term recovery. This study discovered that rural residents’ recovery activities successfully perpetuated their original rural lives and rebuilt social connections and networks both individually and collectively. However, they were only able to manage their agriculture-based livelihood recovery temporarily. This research suggests that engaging rural inhabitants’ place-making expertise and providing opportunities to improve their housing and communities would advance the long-term grassroots recovery of lives and livelihoods, achieving sustainable development.

“…The key factor which can be used to measure the effectiveness of the reconstruction process is by analyzing if the lesson learned from the previous experience has helped in introducing improved and timespecific building codes and programs or not (Yaoxian, 1996). Another aspect of effective reconstruction is through better supervision mechanisms which can be gained through decentralization of rights to the community and also denying the one-right housing reconstruction plan (Li et al, 2019).…”

The reconstruction work following the 2015 Gorkha Earthquake is being done under the leadership of the National Reconstruction Authority (NRA) by various organizations in coordination with donor agencies and the local people. A detailed study regarding the reconstruction work is necessary to analyze the work done measured in terms of technical, socioeconomic, and sustainability parameters so that the lessons learned from the study could be used in future policymaking and implementation process that aids in achieving an earthquake-resilient community. The study aimed to evaluate the technical parameter of the reconstruction work done in the Nuwakot district until May 2020, according to the Nepal National Building Codes and the latest NRA guidelines. The study was based on qualitative data collected through a Google form survey. The respondents included experts who were working or had worked in different capacities at various organizations involved in reconstruction efforts at the Nuwakot district. The survey covered aspects such as the status of site topography and geology, technical supervision, design and construction, training and capacity building, and use of vulnerable buildings. The study revealed that most of the buildings are compliant with the specified codes/guidelines and are structurally safe. There is a need to improve on the other aforementioned aspects of technical parameters to aid in achieving resiliency.
