城市管理公众满意度指数模型实证分析

随着城市化进程的快速推进,公众广泛参与的多元主体管理模式成为现代城市管理的发展趋势,"公众满意"成为衡量城市管理水平、反应城市竞争力的重要指标.本文针对城市管理全民共享、非盈利化以及缺乏消费者自由选择的特点,结合我国城市管理模式地区差异明显这一具体国情,提出了一个区别于企业顾客满意度指数模型的城市管理公众满意度指数模型(UMPSI),并以来自杭州市城市管理公众调查的数据对该模型进行大样本的实证分析,找出了影响城市管理公众满意度的关键因素,较好地解释了城市管理公众满意的作用机理,为城市管理服务质量的改善和政府相关政策的制定提供了具有实际价值的决策参考.     

Demand disruption and coordination of supply chain via effort and revenue sharing

This article explores the equilibrium behaviour of a basic supplier–retailer distribution channel under demand disruption via effort and revenue sharing contract. This differs from the traditional supply chain coordination model. Firstly, demand is simultaneously affected by retail price and nonprice marketing effort from manufacturers and retailers. Secondly, when the demand is disrupted, this article considers disruptions in the market scale and price sensitivity coefficient. Thirdly, the supply chain coordination model is proposed via effort and revenue sharing contract. In this way, the manufacturer reduces the wholesale price as an incentive for the retailer to share revenue. Finally, the total supply chain profit is greater with contract than no contract. This also constitutes another incentive for the players to follow the effort and revenue sharing contract.

多酶分步水解法提高豌豆纤维纯度的研究

以豌豆粉丝废水分离渣为原料,对豌豆纤维的提取过程进行研究。通过耐高温α-淀粉酶、糖化酶、蛋白酶多酶分步水解的方法,去除豌豆渣中的淀粉和蛋白质。结果表明,耐高温α-淀粉酶添加量1.2%,反应温度为90℃,反应时间为60 min的条件下,豌豆膳食纤维的提取率最高;糖化酶加酶量为4.5%,反应温度为60℃,反应时间为110 min,pH为5.0的条件下,可达到良好的水解效果;蛋白酶的加酶量为1.0%,反应温度为55℃,反应时间为80 min,pH为8.5的条件下,酶解效果最佳。此时豌豆粉丝废水分离渣的膳食纤维含量可达到94%以上。     

The culturally contingent meaning of entrepreneurship: mixed embeddedness and co-ethnic ties

This study employs phenomenography to investigate the role of embeddedness in business venturing of migrant and ethnic entrepreneurs. By focusing on two culturally distinct groups, operating in the same micro-economic context, we show the ways in which embeddedness impacts the perceptions and subsequent enactment of business venturing. Our findings demonstrate that, despite physical proximity and similar socio-economic context, the investigated communities predominantly employ their co-ethnic norms, assumptions and frames of reference to makes sense of and act upon entrepreneurial opportunities. These findings expand the mixed embeddedness literature by exploring how co-ethnic sensemaking frames persist within culturally distinct communities, despite years of co-existence within the same socio-economic context. Moreover, our study reveals how co-ethnic structures can successfully substitute institutional arrangements traditionally provided by the host-country environment. By reflecting upon the practice of entrepreneuring and entrepreneurial sensemaking, our findings point towards the importance of language and interpretative methods for theory development.

Quantitative and Dynamic Analysis of the Oli Variables Determining Fdi in China

The main determinants of foreign direct investment in China are analyzed quantitatively and dynamically based on Dunning's eclectic theory and empirical models corresponding to location-specific advantages, ownership-specific advantages and internalization advantage. More specifically, the correlation between each OLI variable and FDI is tested and explained in detail. It is concluded that monopolistic advantages of technology and management experience of foreign investors along with China's low labor cost and great market potential might be important factors attracting FDI in China. In addition, using an internal market to establish a network of international production might also be an important determinant for foreigners to directly invest in China. Others might include searching for attractive yields available in equity investment, devaluation of the Chinese currency, distance, culture and global business strategies.     

提高最低质量标准真的能够增进社会福利吗*

本文通过构建基于纵向质量差异的双寡头竞争模型，分析了最低质量标准政策对质量提升的作用机制及其福利影响。研究结果显示，最低质量标准政策的效果会极大地受到企业之间技术差距和政府监管效率的制约，并且对不同企业会产生差异化的影响。在国内外企业存在较大技术差距的背景下，政府在实施最低质量标准政策时会遭遇降低质量标准或者放松监管的两难困境，并且会在生产者和消费者，以及不同的厂商之间产生利益冲突。解决上述问题的关键在于提升监管效率的同时，缩小国内外企业之间的技术差距。
