政府补贴、市场集中度与种业企业技术创新效率的关系——基于省级面板数据     

陈超  张悦  王迎春  杨扬 《科技管理研究》2021,41(20):87-96

为促进种业技术创新效率提高,基于2013—2018年我国30个省份的种业企业数据,运用DEA-Malmquist模型对企业技术创新效率进行测算和动态分析,并运用面板Tobit模型和门限回归模型分析政府补贴与市场集中度对企业技术创新效率的影响.结果表明:我国种业企业技术创新效率整体偏低,全要素增长率提高主要依赖于技术进步和创新;市场集中度对企业技术创新效率具有负面影响;政府补贴可以促进企业技术创新效率的提高,但效果会受到市场集中度的调节,市场集中度过高会抑制政府补贴的积极效果.基于研究结论,提出加强市场和政府两种手段的协调和控制种业市场集中程度等促进我国种业产业高质量发展的对策建议.  相似文献   

Constructing and analyzing domain-specific language model for financial text mining     

《Information processing & management》2023,60(2):103194

The application of natural language processing (NLP) to financial fields is advancing with an increase in the number of available financial documents. Transformer-based models such as Bidirectional Encoder Representations from Transformers (BERT) have been successful in NLP in recent years. These cutting-edge models have been adapted to the financial domain by applying financial corpora to existing pre-trained models and by pre-training with the financial corpora from scratch. In Japanese, by contrast, financial terminology cannot be applied from a general vocabulary without further processing. In this study, we construct language models suitable for the financial domain. Furthermore, we compare methods for adapting language models to the financial domain, such as pre-training methods and vocabulary adaptation. We confirm that the adaptation of a pre-training corpus and tokenizer vocabulary based on a corpus of financial text is effective in several downstream financial tasks. No significant difference is observed between pre-training with the financial corpus and continuous pre-training from the general language model with the financial corpus. We have released our source code and pre-trained models.  相似文献   

R&D synergy between local and foreign-owned enterprises in post-communist economies     

《国际创新研究学报(英文)》2023,7(2):101-114

This study examines how internal research and development (R&D), external knowledge acquisition, and R&D contracted with other companies interact in local and foreign-owned enterprises in post-communist economies. A large sample of firm-level data from the Business Environment and Enterprise Performance Survey (BEEPS) across 26 post-communist countries (including European Union (EU) members and non-EU states of Eastern Europe, Caucasian countries, and Central Asian countries) and country-level data from the Global Innovation Index and the International Property Rights Index were used. The findings show that enterprises with majority foreign ownership are relatively more likely to acquire external R&D. We demonstrate that the R&D behavior of enterprises with majority foreign ownership and local firms are interrelated, that is, we find a synergy effect. According to the results, decisions on internal R&D and the purchase of external knowledge for enterprises with majority foreign ownership are similar to those of local firms. However, enterprises with foreign ownership contract R&D with other companies more often if local firms conduct internal R&D. These results indicate the presence of knowledge spillover and cross-learning effects in both types of enterprises in post-communist countries. Finally, we find that the national innovation environment is not significant for the R&D intensity of enterprises with majority foreign ownership, which suggests their high dependence on the parent structures of multinational enterprises.  相似文献   

Under the radar: Industry entry by user entrepreneurs     

Stefan Haefliger  Peter Jäger 《Research Policy》2010,39(9):1198-1213

We inductively develop a model of the commercialization process for new products or services user entrepreneurs undertake when entering an industry while drawing on proprietary technology developed in another industry. Extending the growing field of user entrepreneurship, we identify a two-phase approach to industry entry by user entrepreneurs who start “under the radar” of incumbent firms, gain experience, attract a first potential customer base, and then, in a second phase, engage in commercialization. During this process, a community of fellow users is of major importance for the entrepreneur, serving as a knowledge pool for skills development and experimentation with different commercialization paths. We study a nascent group of firms founded by users of video games who became entrepreneurs on entering the animation industry by producing Machinima, a new film genre characterized by shooting film in video games. We explain how user entrepreneurs gain access to complementary assets (video games) for their new use (shooting film), how they deal with intellectual property issues when using other firms’ assets, and how user entrepreneurs combine domain knowledge about film production with their experience in video games and the art of Machinima. Our propositions hold implications for management and policy.  相似文献

我国东西部金融资本配置的帕累托最优分析   总被引：1，自引：0，他引：1  

毛加强  胡忠艳 《科学．经济．社会》2010,28(4):55-59

随着金融资本流动性的加强,金融资本在社会总资本中的重要性日渐明显,而我国金融资本东西部发展十分不均,使得资源配置缺乏效率。本文用经济学中的帕累托理论模型,对我国东西部地区金融资本配置的最优化问题进行分析,结果表明：西部地区金融资本与劳动的边际技术替代率高于东部,我国东西部地区的金融资本配置尚不合理,存在较大的改进空间。本文推导了实现东西部金融资本配置帕累托最优的条件,并从东西金融资本流动、提高西部金融资本积累水平及利用率等方面提出了实现帕累托改进的措施。  相似文献
