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.

본 연구는 노동생산성 향상을 위해 다양한 방식으로 지급할 수 있는 정부 보조금의 효과를 분석하여 비교한다. 노동자들은 학습 능력에 차별화된 분포를 하고, 수요복점의 각 기업은 투입하는 노동의 질적 수준과 임금 수준을 완전정보 하의 두 단계 비협조게임 모형을 통해 순차적으로 결정한다. 이때 질적 수준 및 생산성 측면에서 앞서 있는 기업에 유리하도록 보조금을 지급하면, 이 기업은 노동시장에서의 경쟁력 강화로 임금경쟁 심화를 선호하게 되어, 차별화 정도의 축소를 위해 질적 수준 저하를 시도하고, 상대방 기업은 경쟁력 약화로 경쟁 회피를 위해 차별화를 확대하려고 역시 질적 수준을 낮추려는 유인을 가질 수 있다. 반대로 정부가 낮은 질적 수준이나 저생산성의 기업을 지원하면, 경쟁력 강화로 부터 심화한 임금경쟁을 하기 위해, 차별화 축소의 목적으로 질적 수준을 높일 동기를 갖게 되며, 상대 기업은 차별화 확대를 위한 질적 수준 향상의 유인이 있다. 그리고 지급 대상이 노동자인지 기업인지에 따라 결과에 유의미한 차이는 발생하지 않는다.

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.

우리나라 건설 현장에서는 인적요소인 건설근로자들의 경험과 행동에 따라 노동 생산성이 좌우된다. 건설현장의 노동 생산성을 향상시키기 위해서는 노동생산성을 저해시키는 잠재적인 요인들에 대한 전략적인 관리가 필요하다. 하지만 기존의 노동생산성 관리는 사전에 잠재적인 저해요인들을 도출하여 전략적으로 관리계획을 세우기보다는 현장에서 발생하는 현재적인 저해요인들만을 관리하는데 치중되어 있다. 이에 본 연구에서는 잠재적인 원인을 파악하는데 용이한 IPA를 이용하여 현장별 건설근로자의 노동생산성 저해요인을 비교분석하고자 하였으며, 근로자의 경제적인 문제에 대한 불만뿐만 아니라 근로자의 고용불안과 취약한 근로조건에 대해서 보호받고 있다고 느끼지 못하는 현실적 문제점을 파악 할 수 있었다. 이를 통해 현장관리자에게 실질적이고 현장에 적합한 관리측면의 전략적 시사점을 제시하며, 현장의 특성에 따라 노동생산성 향상의 중 장기적인 대책을 마련할 수 있을 것으로 기대된다.
