In China, the frequent safety accidents in building projects seriously affect the sustainable development of construction projects. The paper makes a statistical analysis on the characteristics of ordinary and more serious accidents in building projects from the types of accidents, the trends of development and the characteristics of geographical distribution from 2005 to 2016 in China by using the histogram, trend chart, pie chart and table. It can be concluded that in the recent 12 years, the security situation of construction projects generally fluctuates in a big way and is still not optimistic. Among the five major types of accidents, the electric shock and the lifting accidents have been maintained at a relatively stable and low incidence, and the sloughing accidents have accounted for more than half of the proportion. Accidents concentrated in East China, Central China, North China and Southwest China. The economic development in all provinces and cities in China is positively related to the accident. The greater the total regional economy, the rate of economic growth and the demand for infrastructure construction, the more deaths and accidents in construction projects in the corresponding regions.

Delay in the execution of construction projects is a major problem confronting the Nigerian construction industry. If unchecked, it will constitute a setback to the realisation of the infrastructure development component of the sustainable development agenda of the United Nations. This paper compared the causes of delay in public and private building projects in Lagos State, Nigeria with a view to enhancing project time performance. The study was conducted using a random sample of 87 Architectural firms and 88 contracting firms out of a population of 289 and 293, respectively in the study area. These represent 30% of the population of Architectural and contracting firms, in the study area. Data were retrieved from 47 Architectural and 48 contracting firms and analysed using mean score and student t-test. Results from the study indicated that delay in public building projects was mostly due to contractor’s financial difficulties with mean score (MS) of 2.84, rise in materials prices (MS = 2.80) and variations (MS = 2.72). On the other hand, client’s interference (MS = 2.92), rise in materials prices (MS = 2.83) and slow decision by clients (MS = 2.74) were the major causes of delay in private projects. T-test also revealed that the respondents were significantly different in opinion on 12 out of the 30 causes of delay in both project types in the study area.

Droughts and hot extremes may lead to tremendous impacts on the ecosystem and different sectors of the society. A variety of studies have been conducted on the variability of the individual drought or hot extreme in China. However, the evaluation of compound droughts and hot extremes, which may induce even larger impacts than the individual drought or hot extreme, is still lacking. The aim of this study is to investigate changes in the frequency and spatial extent of compound droughts and hot extremes during summer in China using monthly precipitation and daily temperature data from 1953 to 2012. Results show that a high frequency of compound droughts and hot extremes mostly occur in the regions stretching from northeast to southwest of China. There is an overall increase in the frequency of co-occurrence of droughts and hot extremes across most parts of China with distinct regional patterns. In addition, an increasing trend in the areas covered by compound extremes has been observed, especially after the 1990s. At regional scales, the increase of the frequency and spatial extent of compound extremes has been shown to be most profound in North China (NC), South China (SC), and Southwest China (SWC), while the decrease of compound extremes was found in Central China (CC). These results show the variability of compound droughts and hot extremes and could provide useful insights into the mitigation efforts of extreme events in China.

The purpose of the study is to develop a model for the co-evolution of the regional economy and economic institutions. The research methods used: abstract-logical for the study of theoretical aspects and the experience of modeling co-evolution; and economic-mathematical for the development of own model of coevolution. The results of the study: approaches to modeling the evolution of economic institutions, as well as the co-evolution of the regional economy and economic institutions are considered, strengths and weaknesses of existing approaches to modeling co-evolution are identified, on the basis of the logistic model and Lotka-Volterra equations, an own co-evolution model has been developed, which includes three entities: regional economy, “good” institution and “bad” institution. Three versions of the model have been developed: the co-evolution of the regional economy and the “good” institution, the co-evolution of the regional economy and the “bad institution,” and a variant of the co-evolution of all three entities simultaneously, in which the “good” and “bad” institutions interact according to the “predator-prey” model, and their the cumulative effect determines the development of the regional economy. Numerical experiments have been carried out in the MathLab, which have shown the capabilities of the model to reflect the results of the co-evolution of the economy of a resource-producing region and economic institutions. In the first variant, a “good” institution promotes economic growth in excess of the level determined by resource availability. In the second variant, the “bad” institution has a disincentive effect on the GRP, as a result of which the GRP falls below the level determined by the resource endowment. In the third variant, the interaction of “good” and “bad” institutions still contributes to economic growth above the level determined by resource availability, but causes cyclical fluctuations in the GRP.

Studying the attention of “artificial intelligence + education” in ethnic areas is of great significance for China for promoting the integrated development of new educational modes and modern technology in the western region. Guizhou province is an area inhabited by ethnic minorities, located in the heart of Southwest China. The development of its intelligent education has strong enlightenment for the whole country and the region. Therefore, this paper selects the Baidu Index of “artificial intelligence (AI) + education” in Guizhou province from 2013 to 2020, analyzes the spatial–temporal characteristics of its network attention by using the elastic coefficient method, and builds the ARIMA model on this basis to predict future development. The results show that the public’s attention to “AI + education” differs significantly in time and space. Then, according to the prediction results, this paper puts forward relevant suggestions for the country to promote the sustainable development of education in western ethnic areas.

Low-carbon economy is a new path which our country is taking to develop economy. As one of the provinces in the southeast coast of China, Fujian develop a low-carbon economy directly relating to the transformation of its economic growth, conservation of energy, improvement of productivity, innovation of technology and so on. We can say that the development of low-carbon economy directly affects the sustainable development of economy and society in Fujian province of China. Therefore, firstly, we believe that government and enterprise should optimize the allocation of resource and improve the utilization of resource. Secondly, the tax policies are supposed to adjust to stimulate the development of environmental protection industry. Thirdly, government should accelerate the construction of infrastructures. Fourthly, the legal system needs to be built and perfected so as to promote the development of low-carbon economy. At last, the investment of techniques is supposed to increase to a certain degree, and the ability of innovation and management of enterprises should be promoted to adapt the development of low-carbon economy of Fujian province.

The Relationship

Background: In order for the post-2015 world development agenda – termed the sustainable development goals (SDGs) – to succeed, there is a pronounced need to ensure that available resources are used more effectively and additional financing is accessed from the private sector. Given that traditional bank lending has slowed down, the development of non-bank financing has become imperative. To this end, this article intends to empirically test the role of non-bank financial institutions (NBFIs) in stimulating economic growth.Aim: The aim of this article is to empirically test the existence of a long-run equilibrium relationship between economic growth and the development of NBFIs, and the causality thereof.Setting: The empirical assessment uses time-series data from Africa’s three largest economies, namely, Egypt, Nigeria and South Africa, over the period 1971–2013.Methods: This article uses the Johansen cointegration and vector error correction model within a country-specific setting.Results: The results showed that the long-run relationship between NBFI development and economic growth is relatively stronger in Egypt and South Africa, than in Nigeria. Evidence in respect of Nigeria shows that such a relationship is weak. The nature of the relationship between NBFI development and economic growth in Egypt is positive and significant, and predominantly bidirectional. This suggests that a virtuous relationship between NBFIs and economic growth exists in Egypt. In South Africa, the relationship is positive and significant and predominantly runs from NBFI development to economic growth, implying a supply-leading phenomenon. In Nigeria, the results are weak and mixed.Conclusion: The study concludes that in countries with more developed financial systems, the role of NBFIs and their importance to the economic growth process are more pronounced. Thus, there is need for developing policies targeted at developing the NBFI sector, given their potential to contribute to economic growth.

One of the most urgent tasks of economic geography in the article is to ensure the sustainable development of the Jabrayil region on new foundations, whose economic and social facilities, which have been under occupation for many years, have been completely destroyed. The initial data collected on the objects destroyed in the area as a result of the analysis and their geographical location can be used as substantive information in the reconstruction activities of the district. As a result of the analysis, the existing potential in the region: favorable transport, new Zangilan and Fizuli centers in the neighborhood, sand, cement raw materials, fertile lands, canals, rivers, hydropower and solar resources will have a significant impact on the rehabilitation and development of farms. As a result of the research, the optimal centers for the location of "smart villages" in the region were identified. The article will focus on the development of local and global transport routes through the region, the use of local mineral deposits and the effective organization of internal and external relations. The information obtained as a result of the research will allow to build the perspective territorial planning of the regional economy on the basis of existing standards. Key words: consequences of occupation, advantages of reconstructed forms of economy, substantiation of centers, features of distribution in the area
