基于灰色关联分析的煤炭资源型城市可持续发展评价

可持续发展是世界性的重要课题,城市可持续发展是其中一个重要组成部分。文章结合资源型域市的相关特征建立一组可持续发展评价指标体系,并以此为纲搜集相关城市数据,最后引用灰色关联分析方法综合评价各城市可持续发展的能力。通过比对分析结论,找出各城市在可持续发展过程中的优势和劣势并分析成因,以此达到相互借鉴、取长补短的目的。分析结论亦可为各城市转型提供思路上的拓展。

黑龙江省木材产业发展影响因素的灰色关联分析

根据11年的《中国林业统计年鉴》和《黑龙江省统计年鉴》数据,对黑龙江省木材产业产品的发展变化趋势进行描述;选择影响发展的主要指标对黑龙江省三类木材加工产业进行灰色关联分析,以产值作为参考数列。结果表明,各指标与不同加工产业的产值的关联度各不相同,企业数量对木材加工及木制品业的产值影响最大,年人均劳动生产率对家具制造业的产值的影响最大,造纸及纸制品业的产品销售率对总产值的影响最大。依据研究结果提出提高木材产业技术含量、推进木材产业集聚发展、保障产业可持续发展等提高产业竞争力的对策。     

城市群产业结构与分工的测度研究——以辽中南城市群为例

城市群产业结构分工及状况如何会必然直接影响其发育程度及其国际竞争力,因此科学合理测度城市群产业结构与分工程度,具有十分重要的实践意义。运用区位熵灰色关联分析方法研究辽中南城市群2009年产业结构与分工状态,得出结论:①宏观层次上,辽中南城市群产业结构总体相似程度较高,产业结构地域分工不明确;②中观层次上,城市群各城市产业结构趋同现象虽然明显,但产业的地域分工已经开始显现;③不同产业与辽中南城市群的相似程度不同。通过上述研究,以期在实践上为辽中南城市群的产业结构调整提供参考意见。     

灰色系统理论的财政支出效益研究——以广东省财政支出数据为例

人均收入的增长是度量财政支出效益的指标之一.考察财政支出各项目与人均收入的关系,不仅有利于提高财政支出资金的使用效果,也利于促进财政资源的配置效率,还有利于强化财政管理、完善单位预算管理.通过采用灰色系统理论对广东省城镇和农村2002-2009年的财政支出与人均收入的关系进行灰色关联度分析,得出如下结论:财政支出确实能够促进人民收入的增长;科技支出在促进广东省人均收入增加方面比其他支出的增收作用明显;教育支出对农村的增收作用比城镇大;基础建设在促进农村增收的作用比城镇小.同时提出了通过提高整个财政支出的绩效、加大对农村教育支出的力度并提高教育支出的边际收益率、增加向低收入群体的社会保障支出、提高农村基础建设投入效率并增强农村基础建设的利用率来有效提高广东省居民收入的财政政策建议.     

A performance evaluation model for international tourist hotels in Taiwan—An application of the relational network DEA

This research utilizes relational network data envelopment analysis to construct a model to analyze the efficiency and effectiveness of international tourist hotels (ITHs) in Taiwan. The different production processes within the hotel are evaluated, as well as the relationships between efficiency, effectiveness, and overall performance. Finally, based on the results, we recommend ways of enhancing the overall performance of the hotel industry in Taiwan.     

An analysis of e-business adoption and its impact on relational quality in travel agency–supplier relationships

This study analyzes how managers of retail travel agencies perceive the antecedents and consequences of adopting e-business in their supplier relationships. A comprehensive model integrating its antecedents and relational effects is developed and empirically tested using SEM. The study surveyed 101 travel agents in Spain. Research findings indicate that customer pressure has a strong influence on e-communication practices. E-communication with the travel agency's supplier and the pressure exerted by the sector are the main antecedents for e-procurement. Effects of e-business on relational quality are contradictory. E-procurement influences negatively on trust. Conversely, e-communication has a positive impact on trust, thus having a favorable impact on perceived reciprocity and travel agent's commitment to its supplier. Main findings indicate that the use of the Internet is largely driven by normative pressures, and this coercive power has a detrimental impact on trust. To avoid such negative consequences, perceived reciprocity is a prerequisite for committed supplier relationships.     

Indian textile suppliers' sustainability evaluation using the grey approach

Textile supply chains consist of multinational garment retailers (customers), garment manufacturers (suppliers), and ancillary suppliers (suppliers to manufacturers). This paper evaluates suppliers' within the Indian textile and clothing industry (both garment manufacturers and ancillary suppliers) using sustainability criteria. Examining a sample of sixty-three suppliers and six sustainability criteria (i.e. discrimination, abuse of human right, child labor, long working hours, unfair competition, and pollution), we categorize suppliers into the three categories of ‘good performer’, moderate performer’, and ‘performance not up to expectation’. Since all the criteria are potentially subjective, we have employed the grey approach for analysis. The results indicate that the criterion of long working hours is a critical one for both categories of suppliers; in the case of garment manufacturers, we found that pollution and unfair competition were the most important criteria. In addition, employing child labor was found to be a critical criterion in the case of ancillary suppliers.
