In recent years, the area of arable land in China has been decreasing year by year. This is in sharp contrast to the massive infrastructure construction program. This raises a question: how to make full use of limited land resources for large-scale construction. Fortunately, the sustainability concept has been increasingly accepted to be a key aspect of engineering design and construction. Based on this important background, concepts of foundation treatment technology development are introduced in this paper. [ABSTRACT FROM AUTHOR]

In the new era of social and economic development and transformation, the development of China's lowpermeability oil fields is also increasing. In this context, due to the relative lack of natural capacity of China's lowpermeability oil fields, this will reduce the production of low-permeability oil fields to some extent. To this end, in order to effectively improve the recovery rate of low-permeability oilfields and improve the mining effect, it is necessary to rationally apply a reasonable injection-production system for low-permeability reservoirs. We will further delay the production of low-permeability oilfields while ensuring sufficient energy for the formations. The speed of the decline. Based on this, this paper mainly analyzes and explores the rational injection and production system of low permeability reservoirs in reservoir engineering methods. [ABSTRACT FROM AUTHOR]

China is in the critical period of building a moderately prosperous society in an all-round way. It is the period of rapid economic transformation and the decisive battle for deepening the reform. China's development is facing new opportunities and challenges. The risk of foreseeable and unforeseen is increasing. Combined with the new coronavirus, (coronavirus disease 2019 is a new type of pneumonia, also named Covid-19) one of the global biological risk events, this paper analyzes the challenges faced by China in the future in response to biological risk, and discusses how to deal with microbial risk in the future, makes in-depth thinking and puts forward suggestions.

Based on theory of convergence, firstly, per-capita GDP difference convergence model of underdeveloped regions and developing regions compared with developed regions are established, then, convergence model of energy consumption intensity difference compared with per-capita GDP difference is built, from which, it is found that China's regional per-capita GDP growth shows convergence trend, and convergence rate of energy consumption intensity is slightly slower than the per-capita GDP. So, it is suggested that the local government should fully consider the convergence characteristics of regional energy consumption difference to guarantee not only economic growth but also energy saving and emission reduction in order to ensure sustained economic growth in the implementation of energy-saving emission reduction strategies.

To analyze the dynamic structure in China’s economic growth during the period 1952–1998, we introduce a model of the aggregate production function for the Chinese economy that considers total factor productivity (TFP) and output elasticities as time-varying parameters. Specifically, this paper is concerned with the relationship between the rate of economic growth in China and the trend in TFP. Here, we consider the time-varying parameters as random variables and introduce smoothness priors to construct a set of Bayesian linear models for parameter estimation. The results of the estimation are in agreement with the movements in China’s social economy, thus illustrating the validity of the proposed methods. [ABSTRACT FROM AUTHOR]

The paper makes use of 2006-2015-tiine sequence as data to build up a two-evaluation index system of the construction of golden waterway of Yangtze River and economy development along the Yangtze River. Through building the cooperated development mode, there is quantitative evaluation of the cooperation development degree of shipping of Yangtze River and the economy along the river. The result shows that the cooperation relationship is in steady upward trend; the cooperation development degree of three regions shows certain feature of crust; the cooperation development degree of 9 provinces and 2 cities in Yangtze River Economic Belt has obvious space difference.
