试论如何降低国有运输企业资产负债率

龙源期刊网 https://www.wendangku.net/doc/0a18066210.html, 试论如何降低国有运输企业资产负债率作者：林洁来源：《财经界·下旬刊》2019年第12期摘要：资产负债率过高制约国有运输企业高质量发展，降低企业杠杆率，是防范化解企业债务风险的重要举措。本文将通过内外部两方面因素，分析国有运输企业资产负债率上升的原因，从完善金融资本市场、减少国有运输企业社会责任、强化内部管控等方面讨论降低国有运输企业资产负债率的策略，促使企业资产负债率尽快回归合理水平。关键词：降低; 国有运输企业; 资产负债率随着新型交通运输组织方式的崛起，国有运输企业面临挑战，高负债率的国有运输企业成本高、利润微，在竞争中处于劣势。中共中央办公厅、国务院办公厅联合印发了《关于加强国有企业资产负债约束的指导意见》，力求降低资产负债率，通过建立和完善国有企业资产负债约束机制，强化内部监督管理，确保降杠杆工作取得实效，实现企业资产保值增值，已成为国有运输企业工作重点。一、降低国有运输企业资产负债率的意义改革开放四十多年，国有运输企业经营规模发展迅速，自身内源积累已无法满足发展所需的资金，需要通过外部融资筹集资金，实现生产经营活动的转型升级。从现状来看，大部分国有运输企业属于重资产公司，如果资金融合和投资利用不完善，长期微利经营，企业利润不足以偿还负债及利息，将造成企业资产负债率节节攀高，严重阻碍经营发展。因此，对国有运输企业资产负债率进行有效控制，重视资金科学规划利用，重视生产经营活动质量，防范财务风险，保持竞争优势，对企业长期高质量发展具有重要意义。二、国有运输企业资产负债率上升的原因资产负债率是评价企业债务风险状况的重要指标。国务院国资委考核分配局编制的《2019年企业绩效评价标准值》中提出，交通运输业（全行业）资产负债率控制标准：优秀值为54%、良好值为59%、平均值为64%、较低值为74%、较差值为89%。传统道路运输企业，新建综合型交通运输场站，发展城乡公交一体化、客运旅游等业务，固定资产投入巨大，资产负债率普遍接近行业平均值。公交运输企业，多靠政府补助实现微利，且大量更新新能源汽车，资产负债率普遍接近行业较差值。航运业运力过剩，需求端呈现持续疲软态势，资产负债率普遍接近行业较低值。资产负债率上升是由企业内外部因素共同导致，外部因素主要有：

人教版九年级Unit2知识点详解

（一）课文详解 1、What a great day!(P9) 本句是由what引导的感叹句。其结构为：What + a /an + 形容词+ 可数名词的单数形式（+主语+谓语+其他） Eg: What a new bike(it is)! What a beautiful girl! 2、But I guess it was a little too crowded.(P9) 1)这是一个含有宾语从句的复合句，I guess为主句，it was a little too crowded为省略了引导词that的宾语从句。在复合句中，当主句为一般现在时时，宾语从句可根据其具体情况使用任意适当的时态。 Eg: I guess he is a policeman. I hear she went to Beijing by plane yesterday. 2)crowded adj.“拥挤的”。常用短语：be crowded with……“被挤满”。crowd v. “拥挤” Eg: The shop near my house is always crowded with people. Hundreds of people crowded into the church. 3、Bill wonders whether they’ll have zongzi again next year.(P9) 1)wonder此处用作既无动词“想知道”，相当于want to know. wonder在不同的句式中表达的意思不相同：后接who,what,why等连接词引导的宾语从句及“疑问词+动词不定式”结构时，意为“想知道” Eg: I wonder who that boy is. 后接if或whether引导的宾语从句时，表示一种委婉的请求或疑问 Eg: I wonder if I could use your mobile phone. 后接that引导的宾语从句以及动词不定式短语时，表示“对…感到惊讶” Eg: I wonder to see her looking so cheerful. wonder n.奇迹，奇观wonderful adj. 壮观的，奇妙的，精彩的 eg: What are the Seven Wonders in the world? We had a wonderful time in the park last Sunday. 2)whether连词，“是否，是不是”，引导宾语从句，相当于if。 Eg: He wonders whether / if it will be fine tomorrow. 辨析: whether if 二者都可以引导宾语从句，意为“是否”，一般情况下可以互换。

国有大型工业企业高资产负债率的原因分析

国有大型工业企业高资产负债率的原因分析资产负债率指标是指企业负债总额占资产总额的百分比，它是企业重要财务指标之一，这一指标反映了在企业全部资产中由债权人提供的资产所占比重的大小和债权人向企业提供信贷资金的风险程度。资产负债率指标反映了企业进行负债经营的潜在能力，而较高的负债率将会使企业经营陷入困境，企业现金流紧张会影响企业正常的经营活动，同时如果无法及时偿还债务，将会使企业陷入破产的危机。由于历史、体制等多方面原因，国有企业普遍存在高资产负债问题，目前已经引起相关部门的广泛关注。在当前中国经济增速放缓、改革面临攻坚期之时，如何有效合理地控制国有企业总体负债规模、降低国有企业资产负债率、牢固国有企业资金链条、防范国有企业经营风险，已经成为当前经济体制改革中的重要问题，也引起了国家的高度重视（徐进，2012）。2011年，中央国资委调整了对高负债央企的界定，认定标准从原来的80%降至75%，并将资产负债率偏高的中央企业划分为重点关注企业（75%-85%）、重点监控企业（85%-90%）和特别监管企业（90%以上），说明中央国资委对央企的高资产负债率问题已经高度重视。一、辽宁省国有大型工业企业高资产负债率现状辽宁省是老工业基地，国有企业数量较多，国有及国有控股工业企业资产占全部规模以上工业企业资产总和的60%左右。辽宁省全部规模以上和国有及国有控股工业企业2008年至2012年的整体资产负

债率（见表1），整体来说辽宁省全部规模以上工业企业的整体资产负债率小幅下降，大致在58%左右，但国有及国有控股工业企业的整体资产负债率明显偏高，呈逐年上升趋势，2012年整体资产负债率为66.25%。考虑到国有企业规模一般相对较大，为了进一步剔除中小规模企业数据的影响，从而能够更好地观察国有及国有控股大型工业企业的资产负债情况，本文选择辽宁统计年鉴的大型工业企业数据（见表2）。辽宁省大型企业中国有及国有控股资产的占比份额更大，说明国有大型企业始终是辽宁省经济的重中之重，相比来说国有及国有控股大型工业企业的平均规模较大，平均在100亿元左右，而外商投资的大型工业企业平均规模较小，大约30亿元左右。表1和表2中的数据都表明，国有及国有控股大型工业企业的平均资产负债率相对更高，而且从时间趋势来看整体资产负债率逐年升高，2008年辽宁省国有及国有控股大型工业企业的整体资产负债率为61.80%（见表2），而2012年达到67.08%，相比外商投资大型工业企业尽管规模相对较小，但整体负债率大致在60%左右。本文进一步观察沈阳统计年鉴中沈阳市国有控股大型工业企业数据来说明问题，选择这一数据的原因有以下几点：首先辽宁省主要的大型工业企业分布以沈阳和大连居多，其次沈阳统计年鉴中提供了范围更广的数据指标，最后是沈阳统计年鉴中的国有控股大型工业企业数的年度变化不大，从而避免了由于企业数量变动较大造成的数据偏误（见表3）。2008年到2011年，沈阳市国有控股大型工业企业发
