同群效应与公司研发*——来自中国的证据

本文研究了“同群公司”的研发支出对公司自身研发行为的影响。研究发现，同群公司研发支出越多，公司自身研发支出也越多。进一步研究发现，在公司与同群公司地理距离较近或同群公司分析师覆盖程度较高情况下，同群公司研发支出与公司自身研发支出的正相关关系更强。此外，同群公司研发支出会提高公司自身研发支出与未来业绩的正相关程度。研究表明，公司会学习同群公司的研发决策，进而改变其自身研发决策，呈现显著的研发支出同群效应；且公司信息解读成本较低时，研发支出同群效应更为显著。本文不仅丰富了关于研发支出影响因素的研究，还拓展了对研发溢出效应的研究。本文的研究结论对公司制定研发决策具有重要指导意义。     

Geography and capital structure

We investigate the impact of geographic location on firms’ capital structure decisions. We find strong evidence that location of a firm influences its capital structure. In particular, we find that centrally located firms have lower leverage ratios than do remotely located ones. Moreover, consistent with the hypothesis that those remotely located firms face more severe adverse selection problems, the effect of geographic location on capital structure is more pronounced when information asymmetry is higher. We further examine alternative explanations of the negative relation between firm geographic proximity and capital structure and show that the financial constraint effect and industry clustering effect do not explain our results.

中国海外耕地投资的区位特征及其影响因素*——基于2000—2016年土地矩阵网络数据

［目的］分析中国海外耕地投资的区位特征及其影响因素，以促进我国海外耕地投资的合理布局，提高农业投资效率。［方法］以2000—2016年中国137宗海外耕地投资项目及其所涉及的35个东道国作为研究样本，运用Spearman相关分析方法，分别以耕地投资面积和耕地投资项目数量作因变量，研究其与各影响因素的相关关系，并用对应分析法进一步探究各东道国的相对优势。［结果］（1）我国海外耕地投资区域集中在东南亚且由周边国家向外扩展，被投资耕地用途多样，投资规模自2004年开始急剧上升，近年来呈下降趋势。（2）我国海外耕地投资以效率寻求型和市场寻求型为主，倾向于资源丰富、与我国距离较近、制度相似、经济关系良好但发展水平不高的国家。（3）根据各地区的比较优势，亚洲国家适合效率寻求型和市场寻求型的企业投资，欧洲和美洲国家适合资源寻求型和战略资产寻求型的企业投资，非洲国家适合资源寻求型、效率寻求型和市场寻求型的企业投资。［结论］中国农业企业应结合企业投资目标和各地区的比较优势，合理选择投资区位，适时转变投资策略与模式，积极防范海外耕地投资过程中的自然风险、政治环境风险和道德风险等，以提高投资效果。     

审计师地理距离对客户公司股价信息含量的影响

从地理经济学视角分析审计师的地理区位特征对上市公司股价信息含量的可能影响，利用2004—2013年中国A股上市公司的数据，实证检验了审计师与客户间的地理距离对客户公司股价信息含量的经验影响关系，并进一步考察了证券分析师与审计监督两种中介组织间的交互效应。研究发现：（1）审计师与客户公司间的地理距离越小，客户公司的股价信息含量越低，因为在中国当前经济社会背景下，地理邻近对审计师独立性的消极影响要强于其对审计师专业胜任能力的积极影响，这导致审计师审计质量降低，影响客户公司股价信息含量；（2）证券分析师对客户公司的关注程度越高，审计师的地理邻近性对客户公司股价信息含量的负面影响越弱，表明证券分析师与外部审计之间主要呈现一种相互替代的关系，证券分析师可以作为一种有效的补充监督机制。     

Search within or beyond the industrial cluster? The effect of perceived competition and knowledge base tacitness on strategic location choices of external knowledge search

ABSTRACT

From a knowledge-based perspective, this paper highlights the need for a framework linking perceived competition of the industry and firms’ strategic location choices of external knowledge search and examines whether the perceived competition increases the propensity of cluster firms to search more widely from extra-cluster knowledge sources than intra-cluster knowledge sources. Furthermore, we emphasise that cluster firms with varying degrees of tacitness in their knowledge base might respond to such competition differently when conducting external knowledge search activities. Using a sample of 310 cluster firms in the Zhejiang Province of China, we find that the cluster firm would increase the propensity for more geographic boundary-spanning search relative to local search while under the pressure of competition. Moreover, the positive relationship between perceived competition and the propensity towards geographic knowledge search is weaker when the tacitness of the cluster firm’s knowledge base is higher. The findings contribute to the understanding of the relationship between competition and the choice of location strategies in external knowledge search.     

中国东北三省与“一带一路”沿线国家贸易格局时空演变

利用2003年~2017年东北三省与"一带一路"沿线国家进出口贸易数据,采用地理集中度、位序变动指数、综合贸易份额指数、HM指数分析东北三省与沿线国家贸易格局及特征的变化。结果表明:东北三省与"一带一路"沿线国家的贸易往来日益密切,贸易总额大幅增加,尽管东北三省与东北亚地区的贸易份额有所下降,但东北亚地区始终是东北三省的贸易重心。东北三省与沿线国家贸易依赖度不断提高,具有明显的不对称性,表现出显著的单向依赖。从进出口商品结构来看,东北三省向沿线国家出口的资源密集型和劳动密集型商品占比下降,技术密集型商品占比有较大提升,出口商品更加多元化,附加值和科技含量进一步提高,进口商品结构相对稳定,主要为资源密集型和技术密集型商品。     

出口经验能助推对外直接投资吗?--基于中国与“一带一路”沿线国家宏观数据的实证研究

以"一带一路"沿线45国2003~2014年数据为样本,实证检验了出口经验能否提升对外直接投资。研究结果显示,出口经验显著提升中国对"一带一路"沿线国家的直接投资。在基准模型的基础上,引入公共治理、能源禀赋和地理区位与出口经验交互项的实证结果还显示,出口经验对直接投资的促进效应随着东道国治理水平提升而提高,对陆上丝绸之路国家的作用显著低于海上丝绸之路国家,而能源禀赋并未直接或间接通过出口经验对直接投资产生作用。这些研究结论说明,企业在不确定性外部环境下进行对外直接投资时,倾向于通过建立出口学习曲线并依此进行直接投资决策。     

Can proactive environmental strategy improve Multilatinas' level of internationalization? The moderating role of board independence

This paper explores the relationships between proactive environmental strategy (PES) and internationalization in emerging markets multinationals from Latin America (Multilatinas). Drawing on the resource‐based view and institutional theory and using a sample of 86 listed firms during the period 2013–2017, we find that Multilatinas with higher tiers of PES are associated with higher degrees of geographic international diversification. Because adopting PES is directly conditioned by institutional pressures to comply with stakeholders' regulations and expectations, Multilatinas that implement advanced PES will be able to achieve a higher level of international presence in foreign markets. Our results also reveal that board independence positively moderates the relationship between PES and geographic international diversification. Specifically, board independence provides Multilatinas with the opportunity to integrate valuable knowledge and expertise and thus to take advantage of implementing advanced PES to achieve even greater levels of internationalization. This study expands understanding of how environmental strategies influence internationalization of firms in the Latin American business context.
