The Impact

This study identified the impact of a seismic shock on technological progress in earthquake-stricken areas (ESAs) using a synthetic control method. Technological progress was measured using the total factor productivity (TFP) and the TFP growth rate. The ESAs after the Wenchuan Earthquake in China were used as an empirical case study; the Solow residual model was used to assess the TFP and the TFP growth rate in 16 districts. Counter-factual dynamics for the ESAs were constructed to exclude the effect of the macro-economy. The research findings indicate that technological progress in the ESAs after the Wenchuan Earthquake improved as a result of reconstruction investments. However, there were differences in the speed of technological progress between ESAs. These differences may be attributed to the differences in the industrial characteristics between ESAs. The study concludes that the technological progress of the secondary industry, such as the manufacturing industry and building industry, is more resilient. This refers to the capacity to resist economic losses after the seismic shock, compared to the tertiary industry, such as the service industry and tourist industry. However, there was a larger long-term advancement in the technological progress in the tertiary industry compared to the secondary industry after the earthquake. With this understanding, ESA governments can implement appropriate strategies to meet both short-term needs and sustainable economic growth.

The Impact

The impact of certain extreme events on the construction index is of greatly importance which could be viewed as a huge turning to the index. In the paper, the Wenchuan Earthquake of China would be chosen as the extreme event and an EMD-based (Empirical Mode Decomposition) analysis approach would be used to test the earthquake’s impact. In the proposed method, a t-test is necessary to prove the significant level which could say the earthquake did have huge influence on the change of the construction index (399235.SZ) measured in Shenzhen stock market. Then the time series would be decomposed into six different modes and one residue which represent different turnings with different fluctuations and an average trend. Different fluctuations are caused by different factors but there is only one or several dominant modes can reflect the impact caused by certain extreme event which is the Wenchuan Earthquake of China in this study. Through a step-by-step analysis based on the EMD-based analysis approach, a simple solution would be obtained to estimate the huge impact caused by the Wenchuan Earthquake on the construction index which we name an EMD-based event analysis method.

The Wenchuan earthquake occurred on May 12, 2008 (Beijing Time) caused great casualty and economic losses, a large number of masonry buildings were damaged in various degrees in this earthquake. The masonry residential buildings are widely used in China, and the study on them is significant. Although the masonry residential building discussed in this paper which was located in the highly intensity region was damaged severely, it hasnt collapsed and has very typical earthquake damage. The story comprehensive seismic capacity indexes are developed to anti-collapse capacity index which are used to calculate anti-collapse capacity of the building, and the results are also used for comparative analysis with the results calculated by means of structure vulnerability analysis. The earthquake resistant capacity of masonry residential buildings are discussed and analyzed. Finally, some reasonable suggestions on the seismic strengthening and reconstruction of this kind of building after disaster have been given.

The Impact

This paper selects the panel data of 16 cities in the Chengdu-Chongqing urban agglomeration from 2005 to 2015, and uses differences-in-differences model to analyze the impact of high-speed railways on the industrial structure and Carbon Emission of the Chengdu-Chongqing urban agglomeration. The results show that the construction of high-speed rail has reduced the proportion of the secondary industry and has a significant role in promoting the development of the tertiary industry. Among them, fixed asset investment increased the proportion of the secondary industry and the tertiary industry, and technology investment decreased the proportion of the secondary industry, and increased the proportion of the tertiary industry, indicating that the improvement of the level of informatization is helpful to the development of the tertiary industry. It is proposed that a more reasonable evaluation system for the economic effects of highspeed rail should be established. At the same time, the impact of high-speed rail construction on the industrial structure is different. When formulating policies, we must not only weigh the spillover effect and siphon effect of high-speed rail, but also give full play to the carbon reduction effect of economic agglomeration.

BackgroundThe factors influencing pubertal timing have gained much attention due to a secular trend toward earlier pubertal onset in many countries. However, no studies have investigated the association between the Great earthquake and early puberty. We aimed to assess whether the Wenchuan earthquake is associated with early puberty, in both boys and girls.MethodsWe used data from two circles of a survey on reproductive health in China to explore the impact of the Wenchuan earthquake on early puberty , and a total of 9,785 adolescents (4,830 boys, 49.36%) aged 12–20 years from 29 schools in eight provinces were recruited. Wenchuan earthquake exposure was defined as those Sichuan students who had not experienced oigarche/menarche before May 12, 2008. Early puberty was identified as a reported onset of oigarche/menarche at 11 years or earlier. We tested the association between the Wenchuan earthquake and early puberty in boys and girls. Then, subgroup analysis stratified by the age at earthquake exposure also was performed.ResultsIn total, 8,883 adolescents (4,543 boys, 51.14%) with a mean (SD) age of 15.13 (1.81) were included in the final sample. In general, children exposed to the earthquake had three times greater risk of early puberty (boys, RR [95% CI] = 3.18 [2.21–4.57]; girls: RR [95%CI] =3.16 [2.65–3.78]). Subgroup analysis showed that the adjusted RR was 1.90 [1.19–3.03] for boys and 2.22 [1.75–2.80] for girls. Earthquake exposure predicted almost a fourfold (RR [95%CI] = 3.91 [1.31–11.72]) increased risk of early puberty in preschool girls, whereas the increase was about twofold (RR [95%CI] = 2.09 [1.65–2.64]) in schoolgirls. Among boys, only older age at earthquake exposure was linked to early puberty (RR [95%CI] = 1.93 [1.18–3.16]).ConclusionsWenchuan earthquake exposure increased the risk of early puberty in boys and girls, and preschoolers were more at risk than schoolchildren. The implications are relevant to support policies for those survivors, especially children, to better rebuild after disasters.

The Impact

How do natural disasters impact political trust in contemporary China and what is the causal mechanism? Existing literature indicates that the severity of disaster, government relief effort and information dissemination are three key factors influencing people’s political trust in the context of acute natural disasters. This study uses the Wenchuan earthquake as a natural experiment and focuses specifically on the survey data collected right before and after the earthquake. It finds that primarily due to the ‘rally round the flag’ effect and extensive media coverage, public trust in government officials at all levels rose significantly after the earthquake. During the crisis, state-run media played a vital intermediate role. The more a citizen was exposed to the official media coverage, the more likely his/her political trust was to increase. However, the division of work in disaster relief among different levels of government resulted in differences in the level of increase in trust. As local-level governments are often directly responsible for the rescue and post-earthquake relief, they gained the highest increase in political trust, while state-level officials gained the least. The short-run upsurge in political trust receded as time went by. Government mobilization and media coverage are core contributing factors to the increase in political trust during the post-disaster period. Nevertheless, the key to consolidating political legitimacy lies in long-term efforts to build good and effective governance.
