Abstract： The report of the Nineteenth National Congress of the Communist Party of China put forward the strategic goals and tasks of accelerating the construction of an innovative country and a world power of science and technology, and technology innovation capability is the decisive factor for building a power of science and technology, and the basic driving force for national economic growth and competition. At present, China has become a big country in science and technology, but the development of science and technology is still in a “big but not strong” situation. On the basis of this, an evaluation index system including 5 first-level indicators and 24 second-level indicators has been constructed. In addition, a preliminary analysis of the horizontal comparison of scientific and technological innovation indicators between China and the United States was carried out to provide support for the construction of China’s scientific and technological power.

Abstract： Phonograms are comprised of a semantic radical and a phonetic radical. The semantic radical usually implies the meaning of a character, while the phonetic radical offers a phonetic clue for the pronunciation of a character. Prior research has indicated that semantic and phonetic radicals each play an important role in phonogram cognition. However, the way in which the 2 kinds of radicals combine to influence both phonogram recognition and the activation process remains a controversial topic. Neighborhood size is one of the most important characteristics of radicals. The differences induced by the neighborhood size of radicals are called neighborhood effects. Prior studies employed various methods to investigate the roles of semantic and phonetic radicals on phonogram recognition and discovered that phonetic radicals have an advantage in phonogram processing. They also found that the neighborhood size of semantic radicals regulated the relative contributions of semantic and phonetic radicals. However, most of these researchers investigated the roles of semantic and phonetic radicals respectively. Only a few investigators have focused on the comprehensive role of semantic and phonetic radicals in character processing. This study attempted to investigate the comprehensive effect of semantic and phonetic radicals on phonogram recognition. Participants’ brain responses were recorded using event-related brain potentials. Four types of characters were selected: HH (phonogram comprised of a high-frequency semantic radical and a high-frequency phonetic radical), HL (phonogram comprised of a high-frequency semantic radical and a low-frequency phonetic radical), LL (phonogram comprised of a low-frequency semantic radical and a low-frequency phonetic radical), and LH (phonogram comprised of a low-frequency semantic radical and a high-frequency phonetic radical). A lexical decision task was adopted; the frequency of the entire character and the number of strokes were equivalent for all groups. The results showed that, for characters with high-frequency semantic radicals (HH and HL), the characters with high-frequency phonetic radicals (HH) elicited a larger P200 waveform component than the characters with low-frequency phonetic radicals (HL). However, for characters with low-frequency semantic radicals (LH and LL), there was no significant difference between the characters with high-frequency phonetic radicals (LH) and those with low-frequency phonetic radicals (LL). Characters with high-frequency phonetic radicals (HH and LH) elicited a larger N400 component than those with low-frequency phonetic radicals (HL and LL), and the N400 differences induced by the neighborhood size of phonetic radicals with high-frequency semantic radicals (HH and HL) were larger than those induced by characters with low-frequency semantic radicals (LH and LL). These results indicate that in the early stage of phonogram recognition, the neighborhood effect of phonetic radicals is regulated by the neighborhood size of semantic radicals. In the late stage of phonogram recognition, the higher the frequency of phonetic radicals, the stronger the semantic activation degree of the character. In general, the neighborhood size of phonetic radicals was found to affect vocabulary accessibility. However, the effect of the neighborhood size of phonetic radicals is regulated by the neighborhood size of semantic radicals. "
