科学与技术耦合效果评价——科技互补效应和成本效应分析

考虑到当前创新环境日益复杂化，科学与技术耦合系统已成为一个受系统内外因共同影响而发生演化的开放系统。在为耦合系统构建状态空间模型的基础上，通过求解该模型，刻画科学技术化强度和技术科学化强度，据此分析科学与技术互动产生的互补效应和成本效应，评价29个省份的科学与技术耦合效果，并测度地区科技发展所属耦合路径类型。研究表明，不同省份推进科学技术化进程和技术科学化进程的差异性显著；科学与技术耦合效果最佳并不能说明地区科技发展速度最快；绝大多数省份的科技耦合路径表现为科技中立路径，占比最小的路径为技术强势路径。基于不同省份的耦合情况差异，提出针对性建议。     

生态政策作用下农户生计资本与生计策略的关系研究*——以内蒙古自治区杭锦旗为例

[目的]探索生态政策作用下农户生计资本与生计策略的关系,对提高农户生计水平,促进区域生态环境修复具有重要意义。[方法]该研究以地处库布其沙漠腹地的杭锦旗为例,基于农户调研数据,对北部沿河区和南部梁外区农户的生计资本和生计策略进行了调查与对比分析,并建立二元Logistic回归模型,对影响两区域农户生计策略选择的关键因素进行了研究。[结果](1)北部沿河区农户的人力资本和金融资本高于南部梁外区,而自然资本、物质资本和社会资本低于南部梁外区。北部沿河区农户选择以农为主生计策略的比例高于南部梁外区,而选择以非农为主的比例低于南部梁外区。(2)人力资本和自然资本是影响两区域农户生计策略选择的共同关键因素。其中,人力资本对两区域农户以非农为主生计策略的选择均具有显著正向影响,而自然资本均具有显著负向影响。比较而言,人力资本和自然资本对生态政策影响较小的北部沿河区农户以非农为主生计策略选择的影响均大于生态政策影响较大的南部梁外区。[结论]杭锦旗农户的生计资本和生计策略具有区域差异性,生态政策是促使农户生计状况产生区域差异的重要因素。在生态政策的作用下,农户的生计策略仍受其生计资本的影响,同时生态政策也通过影响农户可实际运作的生计资本而影响着农户的生计策略。在以上研究的基础上,提出了改善农户生计状况和促进区域生态环境修复的政策建议。     

内外融资条件、融资约束与企业绩效——来自京津冀地区企业调查的新证据*

基于独特的京津冀地区企业调查数据和克服内生性的结构方程模型，本文对融资约束的成因及影响进行了实证分析。分析结果表明，企业自身条件和外部市场环境均对融资约束有重要影响，且企业自身条件对融资约束的影响更强。总的融资约束指标对企业绩效的影响不显著。在区分融资约束的不同维度后，本文发现，融资可得性提高显著促进了企业绩效提升，融资频率增加却降低了企业绩效，而融资获得速度（等待时间）对企业绩效没有统计上的显著影响。进一步的分析表明，无论是正规融资渠道，还是非正规融资渠道，上述结论仍然成立。利用多种政策提高企业的管理水平，改善企业的自身条件，是缓解融资约束的最有效办法。     

Wealth transfer through private placements: Evidence from China

We examine private issuance of public equity (PIPE) in China, and our results suggest that PIPE investors benefit from the price manipulation before and after issuance. These investors tend to cash out after lockup expiration and make large profits. We also find evidence that the trading of PIPE investors after lockup expiration is informed. Tests about the abnormal returns in the 3 years after lockup expiration suggest that at least part of the benefits PIPE investors receive come from wealth transfer from outside investors. Overall, PIPE issuers in China seem to use an opaque mechanism to compensate PIPE investors.     

Buying reputation as a signal of quality: Evidence from an online marketplace

Seller reputation, generated by buyer feedback, is critical to fostering trust in online marketplaces. Marketplaces or sellers may choose to compensate buyers for providing feedback. Signaling theory predicts that only sellers of high-quality products will reward buyers for truthful feedback, especially when a product lacks any feedback and when the seller is not established. We confirm these hypotheses using Taobao's reward-for-feedback mechanism. High-quality products, especially without established feedback, are chosen for feedback rewards, which cause sales to increase by 36%. Marketplaces and consumers can therefore benefit from allowing sellers to buy feedback and signal their high-quality products in the process.     

Does economic policy uncertainty raise corporate precautionary cash holdings? Evidence from China

Using China as the research setting, this paper investigates the relationship between economic policy uncertainty and corporate precautionary cash holdings. Empirical results show a U-shaped relation between economic policy uncertainty and corporate precautionary cash holdings. Empirical analysis, in terms of ownership structure, firm size, corporate competitiveness and geographical location, further shows that (i) the effects for economic policy uncertainty in both state-owned and non-state-owned enterprises are significant, but the effect is stronger for state-owned enterprises; (ii) such significant effect is also found more strongly in small and medium-sized enterprises and highly competitive enterprises; and (iii) the effects for eastern, central and western China are all statistically significant, but the effect is strongest for eastern China.     

土豆红豆鱼香肠的研制

鱼香肠是以鱼肉为主要原料灌制的香肠。它营养丰富、味道鲜美、风味独特,深受广大消费者喜爱,尤其是老人和儿童。鱼香肠的优点是有外包衣(畜肠衣或塑肠衣)使鱼肉与外界隔绝,流通方便,卫生条件较好,加工后可长期保存。本文通过正交实验,探讨土豆和红豆添加量对鱼肉香肠感官质量的影响,逐步确定土豆和红豆的最优添加量,最终确定了新型鱼香肠最优配比为:以鱼肉质量计,土豆添加量:37%,红豆添加量:38%,畜肉添加量:15%,板油添加量:7.5%,淀粉添加量:5.6%,精盐添加量:2.25%,咖喱粉添加量:0.43%,胡椒粉添加量:0.06%,味精添加量:0.2%。     

无溶剂大豆浓缩蛋白的生产工艺

采用物理压榨法制取大豆粉,以此大豆粉为原料,通过酸法改性制取大豆浓缩蛋白,旨在获得无溶剂残留的大豆浓缩蛋白。制得大豆浓缩蛋白的蛋白质含量≥65%、NSI≥70%、脂肪≤1.0%、保油性明显提高。     

结构嵌入、动态能力与组织绩效:一个混合模型

供应链企业对外部关系网络的结构性嵌入，有利于其获取更多异质性资源，这为组织绩效提升奠定了基础。在构建结构嵌入、动态能力与组织绩效关系混合模型的基础上，实证检验了结构嵌入对组织绩效的影响。研究结果表明：结构嵌入与组织绩效间存在显著的倒“U”型关系，即结构嵌入具有“拐点”效应，过高水平的结构嵌入不利于组织绩效提升；环境动态性在结构嵌入对组织绩效的影响中发挥有中介的调节作用；学习能力和创新能力在结构嵌入对组织绩效的影响中存在有调节的中介效应。
