<abstract>
<p>With the continuous development and application of modern logistics technology, logistics cost has become one of the important factors of enterprise competition. For the special field of cold chain logistics distribution, cost control is particularly critical. By studying the control method of cold chain distribution cost, this paper introduces how to reasonably optimize the distribution cost while effectively controlling the distribution cost so as to improve the competitiveness of enterprises. This paper sorts out the relevant theoretical overview and conceptual analysis and analyzes the current situation of cold chain distribution cost control in logistics companies. Then, the existing logistics cost control system is evaluated, and the hierarchical analysis method and model comprehensive evaluation method are used to analyze the current control system score and problems that require additional attention and find the cause of the problem. Finally, rectification suggestions are put forward to improve distribution costs to enhance the competitive strength of enterprises.</p>

<title>1. Introduction</title>
<p>With the continuous expansion of agricultural products and cold chain logistics in the market, more and more cold chain companies have entered the market competition (<xref ref-type="bibr" rid="B1">1</xref>). In order to maintain industry competitiveness, reduce comprehensive logistics costs, and improve customer satisfaction, the control of logistics costs has become the focus of enterprises. Especially in industries such as e-commerce, the status of logistics cannot be ignored (<xref ref-type="bibr" rid="B2">2</xref>, <xref ref-type="bibr" rid="B3">3</xref>). Logistics costs directly affect the company&#x2019;s profits and have a crucial impact on its competitive position. Therefore, controlling the cost of logistics and distribution is of great significance to enterprises. This paper adopts the hierarchical analysis method and the fuzzy comprehensive evaluation method to analyze and evaluate the factors affecting the logistics distribution cost of logistics companies (<xref ref-type="bibr" rid="B4">4</xref>). By collecting data and analyzing the scores of the current control influencing factors, it is found that the cold chain distribution cost module needs additional attention and further sorts out the existing problems and causes and puts forward corresponding rectification suggestions to achieve the purpose of reducing logistics costs. Effectively reducing logistics costs can not only make product prices competitive but also bring more economic benefits to enterprises and help logistics companies improve their logistics service level (<xref ref-type="bibr" rid="B5">5</xref>).</p>

<title>2. Literature review</title>
<p>In view of the research on the cold chain logistics model, Li et al. (<xref ref-type="bibr" rid="B9">9</xref>) pointed out that China&#x2019;s cold chain logistics market is expanding. Through empirical research, they have identified three different cold chain logistics models, namely, self-built cold chain logistics, third-party cold chain, and &#x201C;self-operated + third-party&#x201D; compound mode. Through the analysis of these three different logistics models, we have found out the bottlenecks in the development of cold chain logistics in China and put forward feasible suggestions. In addition, Liu et al. (<xref ref-type="bibr" rid="B10">10</xref>) studied the current situation of cold chain logistics of fresh agricultural products in Guangxi and found existing problems and development bottlenecks. Yu et al. (<xref ref-type="bibr" rid="B11">11</xref>) studied the current situation of cold chain logistics development of more than 100 fresh e-commerce companies, including infrastructure construction and consumer satisfaction, and found that the comprehensive score of the self-built logistics model was the highest. A cold chain logistics model in line with the actual development situation has been established to solve the practical problems encountered on the development road through multiple channels. Zhou et al. (<xref ref-type="bibr" rid="B12">12</xref>) studied the development status of cold chain logistics of more than 100 fresh e-commerce companies, including infrastructure construction and consumer satisfaction, and found that the comprehensive score of the self-built logistics model was the highest.</p>
<p>In terms of cold chain logistics distribution, Chen et al. (<xref ref-type="bibr" rid="B13">13</xref>) conducted an in-depth analysis of the cold chain distribution of pine mushrooms. Combined with the preservation methods of pine antler products and various preservation processes, they studied and discussed the main reasons for the time consumption and inefficiency of logistics and distribution of pine antler products. On this basis, they established a guarantee and a safe urban and rural public distribution service system, with the help of a safe and perfect information sharing system, replanning, and setting up logistics distribution outlets to improve the efficiency of logistics distribution. In addition, Yu et al. (<xref ref-type="bibr" rid="B14">14</xref>) discussed the issue from the perspective of interference management. By measuring the freshness of agricultural products and measuring the distribution service time, they built an acceptance recovery model of logistics distribution and used the start-up algorithm to analyze model requests to provide the efficiency and reliability of high-flow distribution. These studies provide new ideas and methods for the development of cold chain logistics and are expected to be more widely applied and promoted in practice.</p>
<p>In terms of logistics cost control, Chu et al. (<xref ref-type="bibr" rid="B15">15</xref>) pointed out that the use of advanced logistics technology can improve logistics efficiency, which can effectively improve all aspects of the entire logistics service, thus reducing labor and error costs. Zhou et al. (<xref ref-type="bibr" rid="B16">16</xref>) believe that in modern logistics companies, there will be a new development direction, that is, third-party logistics and outsourcing or subcontracting their business. For enterprises, reducing logistics costs is one of the keys to improving their competitiveness. Borgstr&#x00F6;m et al. (<xref ref-type="bibr" rid="B17">17</xref>) pointed out that for today&#x2019;s enterprises, controlling logistics costs is to control the lifeline of the whole enterprise, so it is very important to solve the corresponding cost control problem. Due to the many factors affecting logistics today, attention should be paid to the collection, production, and sales of corresponding products; make full use of modern scientific and technological means to continuously improve the overall logistics and transportation system; and find the best solution. According to He et al. (<xref ref-type="bibr" rid="B18">18</xref>) logistics control is playing a more and more prominent role with the continuous rise of the service industry. It is conducive to adjusting the economic structure, strengthening regional coordination, and continuously enriching economic benefits.</p>

<title>5. Suggestions for improving delivery costs</title>
<p>First of all, we rationally plan the logistics network and transportation routes and reduce unnecessary logistics links so as to reduce logistics costs and improve distribution efficiency. To this end, intelligent technologies such as GPS navigation and logistics big data analytics can be adopted to improve the efficiency of logistics operations while reducing the waste of time and resources. A reasonable delivery route is determined. Whether the delivery route is reasonable or not has a great impact on the delivery speed, cost, and benefit, so scientific methods are used to determine the reasonable delivery routes. In addition, for different cargo types, transportation distances, and timeliness requirements, a variety of distribution methods can be adopted, such as road, rail, and air, as well as express delivery, special line distribution, and self-pickup, so as to flexibly apply and reduce costs.</p>
<p>Second, choosing a more cost-effective logistics service provider is also an important strategy. By comparing with different logistics service providers, we can find more favorable logistics services, and through long-term cooperation, we can also build trust and work together to reduce distribution costs. In addition, strengthening inventory management and optimizing warehouse management is also an important aspect. We reasonably control inventory, reduce inventory costs, optimize warehousing management, improve warehousing efficiency, and reduce warehousing costs.</p>
<p>Finally, in order to improve distribution efficiency and service quality, we can also strengthen the training and management of distribution staff, improve their service awareness and professional level, and adopt a scientific distribution management mode. In addition, the introduction of intelligent logistics equipment, such as automated warehouse management systems, logistics robots, drones, and so on, can improve logistics efficiency, reduce logistics costs, and improve logistics service levels.</p>

<title>6. Conclusion</title>
<p>Based on relevant theoretical research, this paper summarizes the operation process and composition of logistics costs of e-commerce enterprises from the basic definitions and related concepts of logistics cost and cold chain logistics. This paper conducts theoretical research on the logistics of logistics companies on their own logistics, analyzes relevant cases from the perspective of logistics costs, sorts out the problems and causes in logistics control costs, and scientifically evaluates the existing factors affecting distribution costs.</p>
