This study compared the labor productivity of the construction industry to the manufacturing and service industries. In addition, It analyzed the construction labor productivity gap of the G7 countries based on data from the Korean Productivity Center. A comparative analysis of construction labor productivity between manufacturing and service industries, based on statistics from the National Statistical Office, revealed a relatively low level and trend of continued decline. In addition, a comparative analysis of the productivity of construction workers in the major G7 countries found that the difference in productivity is very large, with an average of 65.3 %. Therefore, domestic construction companies and the government should prepare Improvement measures to improve productivity by investing in technology development to increase labor productivity and improving the production system of the construction industry.

Labor productivity issues within the construction industry are receiving increasing attention. With the improvement in the standard of living, domestic laborers are avoiding 3D(Difficult, Dirty, and Dangerous) jobs by degrees. Because of this situation, the problem of insufficient labor is exacerbating in several basic industries. In particular, insufficient labor is a serious problem in the construction sector, where the workers are ageing and labor costs are increasing. In this study, we adopt a systematic approach to identify factors that influence labor productivity and analyze the causality between the factors and their ripple effects with the aim that the results of the study will help improve labor productivity and ensure its effective management. The established labor productivity model using systems thinking will get a footing in the greatest strategy in the construction industry.

In the construction industry, a great deal of research has been focused on productivity improvement because a minor change in labor productivity can often make the difference between a profit and a loss. This study shows how productivity measurement methods can be applied in practice, step by step, to analyze and identify potential problems both in productivity and methods performance for masonry work. A work sampling technique was conducted to determine the nature and extent of an observable activity as an aid to measuring overall performance. Also, a method productivity delay model was used to identify non-productivity in individual cycle times. From the work sampling technique, it was found that the masonry crew had a Labor Utilization Factor of 47.1%, and from the videotape analysis, it was found that the material and dumpster location need to be adjusted to reduce the travelling distance. We have found that efforts to improve the productivity of masonry work should be focused almost exclusively on machine and labor delays, based on the result from the method productivity delay model.

Traditionally, the construction industry has shown low labor productivity and productivity growth. To improve labor productivity, it must first be accurately measured. The existing method uses work-sampling techniques through observation of workers' activities at certain time intervals on site. However, a disadvantage of this method is that the results may differ depending on the observer's judgment and may be inaccurate in the case of a large number of missed scenarios. Therefore, this study proposes a model to automate labor productivity measurement by monitoring workers' actions using a deep learning-based pose estimation method. The results are expected to contribute to productivity improvement on construction sites.

This paper grasped the labor productivity actual condition by the standard of per unit working hour and production about the main products of our country's industrial the main materials and could understand the average of our country's labor productivity as compared this with the labor productivity actual condition of Japan. As the point at issue of analitical result. 1. Low a matter of thinking about productivity. 2. Have a lot of difficult problem in an industrial part. 3. Have the point at issue on technical development and accumulation. 4. Have the point at issue on management. As a countermeasure about these. 1. must convert the way of use of industrial policy. 2. must make a housing development and special serialization of a small and medium enterprise. 3. must establish an organic technical development system. 4. must grope the policy of management rationalization.

In order to improve labor productivity in plants, it is important to grasp the existing problems there. But it is not easy for all the people in charge to have the same level understanding to those. This article suggests an approach to tackle with this situation by using various visualization techniques.

This paper analyzes and compares the effects of various government subsidies to improve labor productivity. Laborers are differentiated in learning ability, and duopsonists in the labor market sequentially determine the quality levels and wages of employed laborers in a two-stage noncooperative game under perfect information. If a subsidy is given to the advanced firm in quality and productivity of labor, that firm will prefer to intensify wage competition due to strengthening its competitiveness in the labor market, and attempt to lower its quality in order to reduce the degree of differentiation in quality. At that time, the other firm wants to avoid competition because of its weakened competitiveness, and may have an incentive to lower the quality level to expand the differentiation. If the government subsidizes low-quality and low-productivity firm, it is motivated to increase its quality level to reduce differentiation due to the strengthening of competitiveness, and its competitor has an incentive to improve the quality to expand the differentiation. And there is no significant difference in whether payments are made to laborers or firms.

Productivity is the essential comparative advantage in high tech industry company in 21 century. These company endless endeavor for low cost production. Low cost production can be led by low facility operation cost and low labor cost. But reducing facility operation cost arise much investment. Thus many high tech company drive reduction of labor cost. These article suggest model for reducing labor cost and prove a effect by example of some company.

Korea's labor productivity in construction sites is dependent on experience and act in accordance with the human element of the construction workers. In order to increase the work productivity of the construction site that requires a strategic management to potentially hindrance factors of labor productivity. However, without considering the potential problems, management of labor productivity in prior studies is focused only on the immediate problems. The purpose of this study is to compare the site-specific analysis of labor productivity impediments using easy IPA to identify potential causes. As a result of the analysis was to identify the realistic problems of job insecurity and poor working conditions as well as economic problems. It is expected that it is possible to provide the basic data to strategy suggestions for long-term labor productivity improvement of the construction site.
