Abstract
China's rapid economic development and its central role in driving globalization have significantly expanded its economic ties with the European Union (EU) over the past few decades. However, in recent years, geopolitical tensions have raised concerns within the EU about whether to further strengthen investment ties with China. This project focuses on a crucial aspect of these economic relations: Foreign Direct Investments (FDI) between China and Germany, one of China's largest investment partners within the EU.

We propose to conduct a randomized information-provision survey experiment to gauge the German public’s opinions on inward Chinese FDIs in Germany. This study will first investigate whether there are significant misperceptions among the German public regarding the actual figures and current status of Chinese FDIs in Germany. Secondly, we will examine the contrasting causal effects of negative and positive narratives about Chinese FDIs versus factual information of Chinese FDIs in Germany on shaping preferences towards these investments.

Given the close bilateral economic relationship between China and Germany, it is equally important to understand Chinese perceptions of German investments. Therefore, we will conduct an auxiliary survey experiment in China to measure the Chinese public's attitudes towards German FDIs in China. Given the relatively favorable portrayal of German investments in China, we aim to observe if there is a significant discrepancy in mutual perceptions of the economic benefits or threats posed by each other.

Primary Outcomes

Primary Outcomes (end points)
The German public's preferences towards Chinese investments, which will be measured on a Likert scale ranging from -5 to 5,
where -5 is strongly disagree, 0 is neutral, and 5 is strongly support. It will also be measured in binary variables indicating whether they select a hypothetical Chinese FDI proposal in Germany compared to other FDI proposals from other EU countries or the US.

Experimental Design

Experimental Design
We will randomly divide our sample into four groups, namely three treatment groups and one control group. The four groups will be of equal sizes. In the first treatment group (T1), the respondents will be shown a positive narrative of inward Chinese FDIs in Germany from German politicians and experts. In the second treatment group (T2), the respondents will be shown a negative narrative of Chinese FDIs in Germany from German politicians and experts. In the third treatment group (T3), the respondents will be asked to state their own perceptions of the distribution of Chinese FDI in Germany, and then they will be confronted with the real figures (belief updates). Afterwards, we will be comparing individuals from each one of the treatment arms respectively with the control group, to show to which extent our respective treatments would alter (decrease or increase) the German public's support for Chinese FDI plans.
Experimental Design Details
Randomization Method
The randomization procedure is implemented by computers by the admin team at the Socio-Economic Panel (SOEP) in DIW-Berlin.
Randomization Unit
The unit of randomization is at the household Level, but the actual data collection will be at the individual level, which means all individuals within the same household will be allocated to the same treatment (control) group. Although the actual implementation will still be at the individual level, in the sense that individuals within the same household won't be jointly administered the same questionnaire at the same time (but rather interviewed separately and independently on his/her own).
Was the treatment clustered?
Yes

Experiment Characteristics

Sample size: planned number of clusters
We will cluster at the household level as well (which is also our unit of randomization). In total, there will be around 1,738 clusters (households).
Sample size: planned number of observations
In total, we will have around 2,365 individual-level observations (which is the unit of data collection), across 1,738 households within the Innovation Sample of SOEP.
Sample size (or number of clusters) by treatment arms
We will have around 590 individual-level observations per treatment arm, and around 435 clusters (households) per treatment arm.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
