This study applies a stochastic frontier production approach to decompose the sources of total productivity (TFP) growth into technical progress and changes in technical efficiency of 8057 firms in Vietnamese manufacturing industries during 2003-2007. Using both total manufacturing industry and sub-manufacturing industrial regressions, the analysis focuses on the trend of technological progress (TP) and technical efficiency change (TEC), and the role of productivity change in economic growth. According to the estimated results, the annual technical progress for the manufacturing industry and sub-manufacturing industries are calculated directly from the estimated parameters of the translog stochastic frontier production function by taking a partial derivative of output with respect to time t. The average technical changes in manufacturing industry and sub-manufacturing industries are positive, with an average technical change about 5.2%, 5.8%, 5.4%, 11.8%, 4.6%, 4.1%, 7.3%, 4.8%, 4.8% and 4.8% for total sample, food products & beverages, textile & wearing apparel, footwear, paper & products, industrial chemicals, rubber & plastic products, non- metallic mineral, basic & fabricated metal and other sub-industries, respectively. Total TFP in the manufacturing sector has grown at the annual rate of 0.052, although the rate of growth decreased continuously during the sample period. For the sub-industry estimates during the sample period, TFP grew fastest in the footwear sub-industry, with annual average growth rate of 11.8%, followed by the rubber & plastic products with a rate of 7.3%, and the food products & beverages with a rate of 5.8% per annum. 展开更多

Through reviewing the development history of reservoir hydraulic fracturing technology, this paper demonstrated the latest research progress at home and abroad and summarized six technical gaps between China and the world, that is fracture propagation mechanism, fracturing software development, fracturing vehicle equipment, downhole tools temperature and pressure resistance, proppant replacement and big data information database. The technical difficulties include lack of geological-engineering deep integration, unclear factors on horizontal well multi-fracture propagation, difficulty in reducing construction costs, environment protection pressure, lack of new experimental and field test equipment, immature techniques for fracturing fluid, and low efficacy of factorized fracturing equipment. We proposed six suggestions on China’s future reservoir hydraulic fracturing technology:(1) strengthen the mechanism study of unconventional reservoir hydraulic fracturing;(2) accelerate the development of geological-engineering integration software;(3) promote the upgrading of EOR fracturing techniques;(4) carry out low-cost multi-functional fracturing fluid formula experiment;(5) complete high-efficiency fracturing equipment;(6) build big database, informational and remote decision-making system of hydraulic fracturing. 展开更多

Combining the development status of information industry in China and based on theoretical discussions on labor demand and supply as well as the comprehensive analysis on endogenous technological progress and exogenous educational quality, this paper concludes that the technological progress of information industry in China is skill- biased, i.e. technological progress of information industry increases the demand for skilled labor while decreases the demand for unskilled labor, and aggravates the wage difference between these two types of labor. Due to the effect of educational quality, the ratio of skilled labor employment to unskilled labor employment will reach a dynamic equilibrium and the wage difference between skilled labor and unskilled labor will not increase continuously. This paper then proves the foregoing conclusion with data of information industry in 26 provinces (autonomous region, municipality). Focusing on typical skill-intensive information industry, this paper mainly studies the influence of educational quality, which not only complements the theoretical analysis on dual effects of technological progress on employment, but also provides feasible and practical basis to policies promoting the development of technological progress and full employment in China. 展开更多

This paper has identified two models of intra-product international division of labor:the model of passive inclusion and the model of proactive participation.Their difference is essentially whether participation in international division of labor is dominated by multinational firms or by local firms.At the level of representative sectors,some characteristic variables of participation in international division of labor demonstrate significant industry differences.Models of division of labor affect technology progress.According to the empirical analysis result at the micro-level of four sectors,no matter for export or the contribution of learning by doing to corporate technology progress,the model of proactive participation is superior to the model of passive inclusion;under the model of passive inclusion,the technology spillover effect of import is smaller than "learning by doing " effect;under the model of proactive participation,technology spillover effect is over two times the "learning by doing" effect. 展开更多

The study analyses the theoretical mechanism through which environmental regulation affects the dairy industry’s technological progress,with a particular focus on how the effect is conditional on farm size.Using the input–output data of dairy farms of different sizes from 2009 to 2019 in 10 Chinese provinces/autonomous regions in China and the quantitative measurement index of environmental regulation,the study estimates environmental regulation’s heterogeneous influences on the dairy industry’s technological progress by dynamic panel data models.The empirical results suggest that,first,environmental regulation has a U-type influence on the technological progress of dairy farming.The U-type influence means moving from pollution control’s high cost and low technology progress to the high profit and high innovation input generated by optimizing the breeding structure.Second,the promotion of dairy farming technology depends on farm size.The effect of environmental regulation on technological progress in moderately large-farms showed a U-type relationship.In contrast,the effect in free-range and large-size dairy farms showed a linear and positive relationship.The government should further strengthen environmental regulation based on advancing moderately large-farms in compliance with market mechanisms in the long run.Particular attention should be paid to the forms of environmental regulation so that dairy cattle breeding technology can break through the inflection point of the“U”curve as soon as possible and ensure the significance of the rising stage.Along the way,technical support should be provided for realizing environmental protection and economic growth. 展开更多

This study reviews the development history of PetroChina’s overseas oil and gas field development technologies, summarizes the characteristic technologies developed, and puts forward the development goals and technological development directions of overseas business to overcome the challenges met in overseas oil and gas production. In the course of PetroChina’s overseas oil and gas field production practice of more than 20 years, a series of characteristic technologies suitable for overseas oil and gas fields have been created by combining the domestic mature oil and gas field production technologies with the features of overseas oil and gas reservoirs, represented by the technology for high-speed development and stabilizing oil production and controlling water rise for overseas sandstone oilfields, high efficiency development technology for large carbonate oil and gas reservoirs and foamy oil depletion development technology in use of horizontal wells for extra-heavy oil reservoirs. Based on in-depth analysis of the challenges faced by overseas oil and gas development and technological requirements, combined with the development trends of oil and gas development technologies in China and abroad, overseas oil and gas development technologies in the future are put forward, including artificial intelligence reservoir prediction and 3 D geological modeling, secondary development and enhanced oil recovery(EOR) of overseas sandstone oilfields after high speed development, water and gas injection to improve oil recovery in overseas carbonate oil and gas reservoirs, economic and effective development of overseas unconventional oil and gas reservoirs, efficient development of marine deep-water oil and gas reservoirs. The following goals are expected to be achieved: keep the enhanced oil recovery(EOR) technology for high water-cut sandstone oilfield at international advanced level, and make the development technology for carbonate oil and gas reservoirs reach the international advanced level, and the development technologies for unconventional and marine deep-water oil and gas reservoirs catch up the level of international leading oil companies quickly. 展开更多

The thoracolumbar spine,due to its large range of motion and relatively fragile anatomical structure,is prone to traumatic fractures and has become one of the common types of fractures in clinical practice.Thoracic and lumbar fractures may lead to spinal instability,spinal stenosis,etc.,and early restoration of vertebral height and sequence is necessary.Although the technique of transpedicular screw internal fixation for traumatic vertebrae is effective in the short term,in the long run,there may be adverse situations such as fixation breakage and loosening,leading to loss of vertebral height and kyphosis deformity.The technique of internal fixation of injured vertebrae with screws is considered to minimize postoperative complications and is worthy of promotion and use.With the advancement of medical technology,imaging,and biomechanics,the treatment methods for thoracolumbar spinal fractures are becoming increasingly diverse. 展开更多

By reviewing the mechanisms of drilling fluid lost circulation and its control in fractured formations, the applicability and working mechanisms of different kinds of lost circulation materials in plugging fractured formations have been summarized. Meanwhile, based on the types of lost circulation materials, the advantages, disadvantages, and application effects of corresponding plugging technologies have been analyzed to sort out the key problems existing in the current lost circulation control technologies. On this basis, the development direction of plugging technology for severe loss have been pointed out. It is suggested that that the lost circulation control technology should combine different disciplines such as geology, engineering and materials to realize integration, intelligence and systematization in the future. Five research aspects should be focused on:(1) the study on mechanisms of drilling fluid lost circulation and its control to provide basis for scientific selection of lost circulation material formulas, control methods and processes;(2) the research and development of self-adaptive lost circulation materials to improve the matching relationship between lost control materials and fracture scales;(3) the research and development of lost circulation materials with strong retention and strong filling in three-dimensional fracture space, to enhance the retention and filling capacities of materials in fractures and improve the lost circulation control effect;(4) the research and development of lost circulation materials with high temperature tolerance, to ensure the long-term plugging effect of deep high-temperature formations;(5) the study on digital and intelligent lost circulation control technology, to promote the development of lost circulation control technology to digital and intelligent direction. 展开更多
