Abstract The selection of excellent partners for enterprises is crucial to the establishment and operation of industrial agglomeration enterprise alliances. It is not only related to the creation of new market values, the reduction of cost of cooperative enterprises, but also directly affects the efficiency of enterprise alliances. This study analyzes the theory of enterprise cooperation under industrial agglomeration, and establishes the index system, selection method and scientific rational selection process of strategic partner selection under this foundation and background , to provide theoretical guidance for enterprises to choose the best strategic partners for industrial agglomeration.

Abstract Nowadays, with the increasingly fierce  c ompetition in the PPP market , the bidding quotation and investment returns are gradually declin ing . This paper systematically analyzes the current transaction structure and payment formulas commonly used in PPP projects, such as the Ministry of Finance formula method, average capital  method as well average capital plus interest method s , and variant forms such as price-tax separation and equity-debt separation  methods . B y comparison , the advantages and disadvantages  of different payment modes are displayed as well as matters needing attention. The Ministry of Finance formula method usually offers little operating subsidy in the early  period and  more  subsidy in the later period, which is difficult for the companies to repay the capital  and interest  in the early period . Due to influence of the discount rate with reference to the local government bond yields during  the same period, the investment returns  are generally not promising and is not commonly  used in actual operation.  The average capital   plus  interest method maintains a stable level of operating subsidies every  year,  and owns a good cap ability to repay the capital  and interest, thus having a  relatively fair investment  return . T herefore, it is the most commonly used method at present. I n terms of the equal capital  method ,  the operating subsidy is usually  huge   in the early  period  and less in the later operation period, which will increase the financial burden  of the  local governments , so it is rarely recognized by the local government in the actual operation. At the same time, this article analyzes the impact of different methods of repaying the capital and interest on the project investment returns . As average capital  plus interest repayment can fully take the advantage of the  low-cost debt to re financ e , the project investment return  is also higher than the  average capital  method in  the same project.

Abstract Based on a systematic consideration of the development dilemmas and outlets faced by state-owned construction enterprises, this paper demonstrates the need for state-owned construction enterprises to carry out cost management during the transition from “incremental expansion” to “intensive development”, and systematically summarizes the main factors of impact of costs management. Combined with the practice of carrying out project red line cost budget management by a China Railway Bureau Group Co., Ltd., it gives suggestions for the implementation of key points and safeguard measures for cost control of construction projects carried out by state-owned construction enterprises.

Abstract This paper systematically elaborates the core of the three major systems of agriculture and the implications for China’s construction. Firstly, the research status of the three major agricultural systems is discussed. On the basis of this, the production function is used to analyze the agricultural production system, and it is concluded that the core of the production system lies in the efficiency of input and output, which depends on many factors; The analysis of the agricultural industrial system though compound function shows that the core of the industrial system lies in the integration and development of the rural one, two and three industries; the implicit function is used to analyze the agricultural management system, it is concluded that the core of the management system is to complete the conversion from product to commodity, and to control the price of the element, agricultural product prices and fluctuations in prices. According to the above research conclusions, it summarizes the enlightenment to China to provide theoretical and decision-making basis for the construction and optimization of China’s three major agricultural systems.

Abstract At present, domestic research on rural revitalization mostly focuses on countermeasures and evaluation indicators, and there is little concern about rural performance evaluation. Based on the value engineering theory, this paper constructs the performance evaluation index system model of rural revitalization project, and applies Shapley method, triangular fuzzy number method and fuzzy comprehensive evaluation method to perform indicator weighting and quantitative aggregation of data of the functional elements and cost, and uses the value coefficient as the evaluation criteria of the performance level of rural revitalization project, in order to judge the level of performance of rural revitalization project, analyze the resource utilization efficiency in the implementation process of rural revitalization project, and then point out the direction for the performance optimization measures of rural revitalization project.

Abstract Litchi is a kind of fruit with high demand for freshness, and the freshness of litchi is lost very quickly. There is no cooperative decision -making mechanism for litchi supply chain in Zhangzhou ,  and the members of the supply chain make decisions independently in most cases. The members of the supply chain make decisions based on their own interests, so that the freshness of litchi cannot be well controlled, and the overall benefit of litchi supply chain cannot be maximized. On the basis of analyzing the supply chain structure and the preservation cost of litchi supply chain in Zhangzhou, this paper demonstrates the necessity of collaborative decision-making on preservation cost control of litchi supply chain in Zhangzhou through an example, and put forward to implement the collaborative decision-making on preservation cost control of litchi supply chain in Zhangzhou by constructing the collaborative decision-making platform of litchi supply chain in Zhangzhou.

Abstract Since the reform and opening up, the civil aviation industry has accelerated its pace of development and achieved world renowned achievements. It has been the world’s second largest civil aviation transportation market for many years. With the rapid development of the civil aviation industry, the construction of transportation airports has always maintained a rapid development trend, the number of airports and business volumes continue to increase, and the annual passenger throughput has basically maintained a double-digit rapid growth. However, at present, the popularity of China’s aviation market is not high, the situation of insufficient capacity of regional airports and large losses has not changed, and a balanced and coordinated development of the airport system has not really taken shape. If China is to move from a major aviation country to an aviation power, it must make up for the shortcomings of insufficient regional airport development as soon as possible. The regional tourism airport is the main component of the regional airport and the most active part of the development of regional airports. It complements the development of regional airports and focuses on accelerating the development of regional airports. Airport A was completed and opened to traffic in May 2017. It is a young and distinctive regional tourist airport. The annual passenger throughput has jumped from more than 100,000 passengers to more than 500,000 passengers in 2019. In the operation process, there are many worth learning from local. Especially in terms of cost control, Airport A creates “airport+” tourist traffic to improve passenger throughput, promotes a transition to management to adjust and optimize the cost structure, green planning and construction to reduce resource and energy consumption, and combines supervision with services to enhance the effectiveness of financial supervision, all of which give a good inspiration for other regional tourism airports to improve cost control.
